Differentiating trig functions with powers
WebDec 20, 2024 · SolutionWe write. For the second integral let and . The integral becomes. We see that if the power is odd we can pull out one of the sin functions and convert the … WebHere we're just going to use some derivative properties and the power rule. Three times two is six x. Three minus one is two, six x squared. Two times five is 10. Take one off that exponent, it's gonna be 10 x to the first power, or just 10 x. And the derivative of a constant is just zero, so we can just ignore that.
