 Hi and welcome to the session. I am Deepika here. Let's discuss the question. Differentiate the function with respect to x. Function is sin of ax plus b. So let's start the solution. Let y is equal to our given function that is y is equal to sin of ax plus b. Now we will differentiate this function by using chain rule. So dy by dx is equal to f of ax plus b into d by dx of ax plus b. So this is equal to x plus b into a. Therefore the answer for the above question is a cos ax plus b. I hope the question is clear to you. Bye and take care.
