    i need to solve the following equation: sin(x+pi/4)=sqrt2*cosx ... For when 0<x<2pi I only got as far as expanding the LS of the equation and then moving the functions around. I am still trying to figure it out, but help would be greatly apprectiated

    I need help with this equation that reresents a windmail. the top is point p. y=2cos(30x)+6 I need to find out how long it will take for point p to reach the height 4.5 meters for the sixth time. it takes 12 seconds to make a full rotation. If you can dont give me the answer for 4.5, use a different number if you can.
