Principal Value | Inverse trigonometric functions | Class 12 | Nitin Vairal Sir Hi, students.. In this video we'll Discuss : Very important topic of Trigonometric function chapter that is Principal Value of Inverse Trigonometric Functions. In Some previous lecture We study How to find Principal solution of trigonometric functions. So firstly we discuss what is Principal Value of Inverse Trigonometric Functions. 1️⃣ Definition : the principal value of a inverse trigonometric function at a point x is the value of the inverse function at the point x , which lies in the range of principal branch. Now discuss, How to find Principal Value of Inverse trigonometric functions ? Now I have mention some following steps , let's learn it : - Consider Principal value of given inverse Equation or inverse function is x. - If given inverse Trigonometric function is Positive form then we Direct find valve of x. - If given inverse Trigonometric function is Negative form then we firstly consider for inverse function of positive term. And find its angles. - Next we choose correct allied angle Formula. - Solve some calculation and we get value of x . - Now we check This value of x which belongs to the range of given inverse Trigonometric function. - If it belong in to range of given inverse trigonometric function then this value is principal Value or principal Solution of inverse trigonometric function. - If it doesn't belong in range of Trigonometric function then it's not principal Solution of inverse trigonometric function. ⚠️ Remember That : Trigonometric Allied Angle Formulas , Values of trigonometric angles And Range of Inverse Trigonometric Functions. So watch video And get detail knowledge of this topic. 👉 Topics : - Principal Value of Inverse Trigonometric Functions. - Find Principal Value of cot Inverse (-1/√3) - How to choose Allied Angle Formulas - Find the value of tan^-1(1)+cos^-1(1/2)+sin^-1(1/2) - Find the value of cosec^-1(-√2)+cot^-1(√3) 👉 TIMESTAMPS : 00:00 Intro 00:09 Discuss Previous Topic : Principal Value of Inverse Trigonometric Functions 01:23 Ex.1.

How to prove projection rule through Cosine Rule | Derivation of projection rule | Trigonometric Function Chapter | Nitin Vairal Sir. Students in Previous Lecture We discuss and prove Most important rule in Trigonometry that is Sine and Cosine Rule. So in this lecture We study last Rule, that is Projection Rule. We discuss following Two concept. 🔶 What is Projection Rule : Projection Rule is the length of any side of a triangle is equal to the algebraic sum of the projections of other sides upon it. 🔶 How to Prove Projection Rule : Basically Here We completing this proof by various methods. but here we Prove Projection Rule Proof by using Cosine Rule. lets Discuss How...? 👇 1) Write Cosine Rule. 2) Simplify this Cosine Rule for Cos functions. 3) Write any one Statment of Projection Rule. 4) Consider its Right Hand Side and Put cos function term in Right Hand Side of Projection Rule. 5) After Simplification , We get Left hand side of Consider projection rule Statment. 6) therefore Left hand side is equal to Right Hand Side. Similarly we can Prove remaining Statements of Projection Rule. 🙏🙏 👇 Lecture Chapters 👇 00:08 Sine and Cosine Rule Discuss 01:19 Projection Rule Proof 04:51 How to Remember and write cosine Rule 06:46 Consider 1st Statment of Projection Rule 10:32 Simplify Cosine Rule for cosB and cosC 14:33 Put cosB and cosC in Projection Rule Statment 18:05 Inshort Explanation of Projection Rule 🙏🙏 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 Thank you for watching this video Lecture.

Cosine Rule Proof | How to prove Graphically Cosine Rule | IMPORTANT Theorems of Solution Triangle | Nitin Vairal Sir. #nitin_vairal_sir #Cosine_Rule_Proof #Trigonometric_Function_Chapter Students in previous lecture we discuss Sine rule Proof. Now in this video we discuss Next Rule . that is Cosine Rule of Trigonometric function. Using this rule we find Solution of Triangle. So How to prove..? it's very easy .. in this Rule Only Remember It's figure. And we Prove whole proof by Using Figure. Basically this figure is a triangle on the XY plane. But how to construct this triangle. Use following steps : 1) Draw xy Plane. 2) Construct a triangle on a plane such that Base of triangle on X axis and one point is on Origin. 3) Give the name of vertices of triangle. A, B, C. which is also Angles of that triangle. 4) Next Opposite side Angle A, B, C is a ,b ,c respectively. Next, By Drawing this triangle. For proof We Choose any Statment of Cosine Rule. Cosine Rule Statment : 1) a²=b²+c²-2bc.cosA 2) b²=a²+c²-2ac.cosB 3) c²=a²+b²-2ab.cosC Here we choose 1st Statment. Consider its LHS and Simplify it by using distance formula.. after Simplification we get RHS of 1st Statment. Similarly we can prove remaining Statements. 👇 Lecture Chapters 👇 00:08 (Previous Lecture) Sine Rule Discuss 01:01 Cosine Rule Proof - 03:25 How to construct figure to prove Cosine Rule - 13:31 Consider 1st Statment (LHS) of Cosine Rule - 18:16 Apply Distance formula 26:17 Inshort Explanation of Cosine Rule 34:24 How to remember And Write Cosine Rule 🙏🙏 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 Thank you for watching this video Lecture.

How to prove Sine rule | Sine Rule Class 12th | Trigonometric Functions Chapter | Nitin Vairal Sir. #nitin_vairal_sir #Sine_Rule_Proof #Trigonometric_Function_Chapter Students in Previous Lecture We Discuss Polar and Cartesian Coordinates Concept in trigonometry. Today In this Lecture we discuss new IMP Topic ,That is Solution of Triangle in Trigonometry. In Solutions of Triangle there are three Important Rules. And Using this rule we Simplify Solutions of Triangle. So firstly we discuss What is Solutions of Triangle. Solutions of triangle means , in a triangle there are three Sides and Three Angles Means total six part. So we find any part of that triangle by the help of Some Important Rules. Now Study This Rules. Totally Three Rules. which are Sine Rule, Cosine Rule, Projection Rule. In this video Lecture we discuss Sine Rule Proof. Which is very important for exam point of view. In sine Rule , we prove this rule by three cases. First is Acute angle A. In Second condition Consider Acute angle B and in last case we consider acute angle C. From this cases We find Hight of triangle remember that for each case we construct separate figure of triangle. also we find Area of triangle. Solving this two equation we get new three equations , Divided this three equations by abc . and we get final result.🤗 👇 LECTURE CHAPTERS 👇 00:08 (Previous Lecture Discussion ) Polar and Cartesian Coordinates Concept 01:15 Introduction to solution of triangle 07:57 Sine Rule Proof - 15:18 First Case : Acute angle A - 24:32 Second Case : Acute angle B - 30:17 Third Case : Acute angle C 40:27 Inshort Explanation of Sine Rule 🙏🙏 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 Thank you for watching this video Lecture.
