Question about Office Equipment & Supplies
I am trying to solve a calculus problem using integration with sinx and cos x. Evaluation, from 0 to Pi/4, in equation (4 cos x + sqroot 2 sin x) dx. I get so far but when I try to evaluate, say, 4 sin Pi/4 I cannot arrive at the given answer of 4/sqroot2. What am I doing wrong with my calculator? My answer is 2sqroot2! Thanks for your help and a Happy New Year.
4/sqroot2 is the same value as 2sqroot2, about 2.828 . It's just a matter of how the calculator and the textbook chooses to represent the value.
