Whilst on scholar i was given te question find the min and max values of (5sin(x)-2)^2)+3. How would you do this

From a sine graph, the maximum value of sin x = 1 and the minimum value of sin x = -1
If you substitute these in you'll get you max and min values for the expression.

give sin(x)=1 for max and sin(x)=-1 for min
