 Hello and welcome to the session. My name is Ashur and I am going to help you with the following question which says find the derivative of the following functions and it is to be understood that A, B, C, D, P, Q, R and S are fixed non-zero constants and M and N are integers. The 14th one is sin x plus A. Let's start with the solution and let us denote the given function by y. So we have y sin x plus A. We have to find its derivative that is d by upon dx. It is given by d upon dx of sin x plus A and derivative of sin theta with respect to theta is cos theta. So here we have cos x plus A into derivative of x plus A. So this is further equal to cos x plus A into derivative of x is 1 and derivative of A with respect to x is 0 since A is the constant we are given. Therefore it is further equal to cos x plus A. Thus I am differentiating the given function and answer is cos x plus A. So this completes the session. Bye and take care.
