We are given:
Differentiate term by term. For the first term use:
For the second term:
And for the third term:
In the above formulas, k is an arbitrary constant.
Hi, I need help finding the derivative for the problem h(x)= x/2^(1/2) + cos x - 2^(1/2)/2. I think the derivative of cos x is -sin x and -2^(1/2)/2 should be 0 because of the constant rule but what are the steps for the derivative of the first part of the problem? The book I'm using only gives the answer and no explanation. Thank you.
