as the title says... how would I input sin^0.5 0.174 into a calculator?
The question is to integrate, using the trapezium rule: - sin ^0.5 x .dx with 6 intervals of equal width. The boundaries are pi/2 and pi/6. Now, I have setted up a table, but dont know how to substitute the x value into sin^0.5 x???
