WebApr 14, 2024 · It can be used to calculate derivative of a function that is complex to solve. Since cos(t 2) is impossible to integrate by using formal integration. Therefore, we will use Taylor’s series to find the integral of cos(t 2). Proof of integral of cos t2 by using Taylor’s Series. Since we know that the integration is the reverse of the derivative. WebMay 5, 2024 · To get the result you could take the square root of both sides and then differentiate with respect to θ to get the final result, but this leaves more room for making errors when doing the differentiation. Taking the square root of both sides in s 2 = R 2 + r 2 − 2 R r cos θ gives s = R 2 + r 2 − 2 R r cos θ.
