WebMay 8, 2024 · Step-by-step explanation: There is a trigonometric identity that states that: sin²θ + cos²θ = 1. Now, for the given we have: (sin²θ + cos²θ) (sin θ + cos θ) Applying the above identity, we would find that the expression becomes: (1) (sin θ + cos θ) which is equal to sin θ + cos θ.

Take the Pythagorean Identity cos2 (θ)+sin2 (θ)=1 and Chegg.com

WebTo test for symmetry with respect to the pole, first replace r r with − r, − r, which yields − r = 3 sin (2 θ). − r = 3 sin (2 θ). Multiplying both sides by −1 gives r = −3 sin (2 θ), r = −3 sin (2 θ), which does not agree with the original equation. Therefore the equation does not pass the test for this symmetry. WebHence, sin(θ)^2 means "take the value of θ, square it, and THEN find the value of the sine function." which is very different from sin^2(θ) which means "find the value of the sine function for θ and then square the result". Note that sin^2(θ) and [sin(θ)]^2 are equivalent expressions. Also, sin(θ^2) and sin(θ)^2 are equivalent expressions. philips garage columbiaWebMar 1, 2024 · 1. Evaluate Sin(90° – θ)? To evaluate sin (90° – θ), we have to consider the following important points. (90° – θ) will fall in the 1st quadrant. When we have 90°, “sin” will become “cos”. In the 1st quadrant, the sign of “sin” is positive. Considering the above points, we have. Sin (90° – θ) = Cos θ. 2. Evaluate ... philips gas module

WebAnalysis. This answer looks quite different from the answer obtained using the substitution x = tanθ. To see that the solutions are the same, set y = sinh−1x. Thus, sinhy = x. From this equation we obtain: ey − e−y 2 = x. After multiplying both sides by 2ey and rewriting, this equation becomes: e2y − 2xey − 1 = 0. WebSince sin (− θ) = − sin θ, sin (− θ) = − sin θ, sine is an odd function. Since, cos (− θ) = cos θ, cos (− θ) = cos θ, cosine is an even function. The other even-odd identities follow from …
