Find x from the following equation cosec(π/2 θ) x cos θ cot(π/2 θ) = sin(π/2 θ) asked Jun 4 in Trigonometry by Daakshya01 ( 297k points) trigonometric functionsLet's start with the left side since it has more going on Using basic trig identities, we know tan (θ) can be converted to sin (θ)/ cos (θ), which makes everything sines and cosines 1 − c o s ( 2 θ) = ( s i n ( θ) c o s ( θ) ) s i n ( 2 θ) Distribute the right side of the equation 1 − c o s ( 2 θ) = 2 s i n 2 ( θ) =cos π/4 ∵ cos(2nπθ)= cosθ , n ∈ N =1/√2 (xiv) sin (151π/6) Solution sin (151π/6) = sin (25ππ/6)

Thinking of θ as an acute angle (that ends in the 1st Quadrant), (π/2θ) or (90°θ) ends in the 2nd Quadrant where only sine of the angle is positive The (π/2θ) formulas are similar to the (π/2θ) formulas except only sine is positive because (π/2θ) ends in the 2nd Quadrant sin(π/2θ) = cosθ cos(π/2θ) = sinθ tan(π/2θ) = cotθ sin(π/2θ)の考え方がわかりません。 僕なりの考え方は sin(π/2θ)=ーsin(θπ/2) に変形して単位円を使い座標が (x,y)から(y,x)に変わるから sin(π/2θ) =ーsin(θπ/2) =ー(ーcosθ) =cosθ という風に考えていて、これでは複雑で大変なので、もっと簡単で単純な解き方はないかなと思って質問しました。 As tan (−θ) = − tan θ, we have, => tan 2θ = tan (θ − π/2) We know if tan θ = tan a, the general solution is given by, θ = nπ a ;
