What is the value of cos(40°) given sin(20°)? The value ofcos(40°)is0.766. To arrive at this result, we find cos 2 theta via the formulacos(2θ)= 1 - 2sin²(θ)forθ = 20°. Plugging insin(20°) = 0.342, we obtaincos(2θ)= 1 - 2×0.342² = 0.766, as clai...

looked at the formula for sine, which is sin(2x) = 2sin(x) cos(x). Then we looked at cosine, which is cos(2x) = cos^2(x) - sin^2(x). Finally, we looked at tangent, which is tan(2x) = 2tan(x) / (1 - tan^2(x)).Read Double Angle Formula | Sin, Cos & Tan ...
The trigonometric identity Cos A + Cos B is used to represent the sum of sine of angles A and B, Cos A + Cos B in the product form using the compound angles (A + B) and (A - B). Understand the cos A + cos B formula using examples.
