the functon is wrong on the picture this is the right one:

a) f(x)=a*cos( /2 *x-b)+2

b) ....... where [0,2) and.....

(a) The function f is given by f(x)=acos(b)4+2 where a>0 and b[0,2).f has a maximum (top point) at the point (3,5). Use this to determine a and b. Here you must clearly show how you have proceeded and reasoned to find the answer. (b) Consider the equation 6sinx+8cosx=m, where x[0,2) and mR is a real number. Determine the number of solutions to the equation for different values of m. (a) The function f is given by f(x)=acos(b)4+2 where a>0 and b[0,2).f has a maximum (top point) at the point (3,5).
