    lease help me this problems ;

    1. Find the maximum value of 1/√cosx + sinx + 5 , and the value of x where the maximum value occurs.

    2. Solve the equation 10sin^2 (1/2x) - 5sinx = 4 , giving the values of x between 0 and 360 to the nearest 0.1

    Thank You in anticipation

    1. Sorry about the late reply. deep in my own studies right now. Alright, let's see here.... maximum of that....

    -that's y= 1/√cosx + sinx + 5 , I'm assuming. So the maximum will be at a point where the gradient is 0. that is, dy/dx=0
    So we have to work out dy/dx of this equation.

    Can you double check these questions. I haven't looked at the second question, but the first seems too complicated to be right.
    I'll reply as soon as you get back to me on these
