Review Trigonometry is the branch of mathematics that deals with the properties of triangles and calculations based on these properties. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
Prove that tan4θ + tan2θ = sec4θ - sec2θ - GeeksforGeeks
WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. 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. hags asterix
