Y=sin(θ+π/2)
Y=sin(θ+π/2)-Let'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) Find real θ such that (3 2i × sin θ)/(1 – 2i × sin θ) is imaginary (a) θ = nπ ± π/2 where n is an integer (b) θ = nπ ± π/3 where n is an integer (c) θ = nπ ± π/4 where n is an integer (d) None of these Answer Answer (b) θ = nπ ± π/3 where n is an integer Hint Given,

The trigonometric R method is a method of rewriting a weighted sum of sines and cosines as a single instance of sine (or cosine) This allows for easier analysis in many cases, as a single instance of a basic trigonometric function is often easier to work with than multiple are The R method is most often used to find the extrema (maximum and minimum) of combinations of trigonometric삼각함수의 각의 변환 두 번째예요 삼각함수 각의 변환 1 2n π ± θ, θ 에서는 θ 가 2n π θ 일 때와 θ 일 때를 공부해봤는데요 이 글에서는 θ 가 π ± θ 일 때와 일 때를 공부할 거예요 삼각함수는 기본적으로 sin, cos, tan의 세 가지인데, 거기에 π ± θ 와 로 네 개의 각이 나오죠?Where sin 2 θ means (sin θ) 2 and cos 2 θ means (cos θ) 2 This can be viewed as a version of the Pythagorean theorem, and follows from the equation x 2 y 2 = 1 for the unit circle This equation can be solved for either the sine or the cosine

Sin (π/2theta) = cos theta As π/2theta lies in the second quadrant so the answer will be in positive as it is lying in sin (second quadrant) and because of π/2 the sin will convert into cos thetaSub your expression for \sin (\theta) In the second equation you can use cos(θ)2 = 1− sin(θ)2 and get a quadratic in sin(θ), solve that for sin(θ) in terms of y(θ) Sub your expression for sin(θ) Transform complex exponential integral to real Transform complex exponential integral to realHow to find Sin Cos Tan Values?
