Calculus 7 Limit Definition of a Derivative

Daily Integral 103: First thing you should do when looking at this problem is to use the double angle identity for sin(2x). Afterwards, you need to be clever and think about how to approach the problem with the proper method. A sneaky way to go about this is to multiply the top and bottom inside the square root by sinx and you’ll notice that one of the sinx can come out of the root leaving us with cotx. It’s a simple u sub moving forward to completely solve this problem. #dailyintegral #integral
