WebWhat is the integral of sin^3 (theta) ? The integral of sin^3 (theta) is -cos (θ)+ (cos^3 (θ))/3+C. WebMar 27, 2024 · There are two formulas for transforming a product of sine or cosine into a sum or difference. First, let’s look at the product of the sine of two angles. To do this, we need to start with the cosine of the difference of two angles. cos ( a − b) = cos a cos b + sin a sin b and cos ( a + b) = cos a cos b − sin a sin b cos ( a − b) − cos ...
