will award best answer circular functions help?
State the equation of the sinusoidal function if a maximum point is (-2,10), and the next minimum is (8,-4). Angles must be in radians.

'Misha' , the 2 points indicate the period is 20..( thus 2π(x-a) / 20 is the angle designation ) and the amplitude is 14/2 and the 'mean' line is y = 3....thus
y = 7 cos ( (π / 10) ( x + 2) ) + 3
