Let us look at the RHS only (It is fine to manipulate both sides but it is usually preferred if you manage to make one into the other) $$ \frac{\cot{\theta}1}{\cot\theta 1} = \frac{\frac{\cos\theta}{\sin\theta}1}{\frac{\cos\theta}{\sin\theta} 1} $$ Now we multiply the numerator and denominator by $\sin\theta$ to get, \begin{equation} \frac{\cos\theta\sin\theta}{\cos\theta \sin\thetaProve That 1tan^2 theta/cot^2 theta1=tan^2 theta Maths Introduction to Trigonometry NCERT Solutions;Sin^2 Theta Cos^2 Theta = 1 Tan^2 Theta 1 = Sec^2 Theta 1 Csc^2 Theta = Cot^2 Theta 1/csc^2 Theta 1/sec^2 Theta = 1 I And III Only II And III Only I, II, And IV Only None Of Those Are True All Of Those Statements Are True

In various applications of trigonometry, it is useful to rewrite the trigonometric functions (such as sine and cosine) in terms of rational functions of a new variable These identities are known collectively as the tangent halfangle formulae because of the definition of These identities can be useful in calculus for converting rational functions in sine and cosine to functions of t in order · See the explanation LHS=(sin^2 theta cos^2 theta cot^2 theta)/ (1 tan^2 theta) We will use the following identities >sin^2theta cos^2theta=1 >1tan^2theta=sec^2theta >1cot^2theta=csc^2theta =>(1 cot^2 theta)/ (sec^2 theta) =>(csc^2 theta)/ (sec^2 theta) =>(1/sin^2 theta)/ (1/cos^2 theta) =>cos^2theta/sin^2theta => cot^2 theta=RHS · Prove that 1 tan² θ = tan²θ cot² θ 1Class X MathsTrigonometryImportant Question#DailyPracticeProblem
