Hello.
a- Express 5sinx+ 12cosx in the form Rsin(x+A)
a- Find the Maximum and Minimum values of f(x) where
f(x)= 1 / ( 5sinx+12cosx+17). State also the values of x in the range of x is greater than 0 less than 360 degrees, at which they occur.
I can do part a) My answer is 13sin(x+67,4)
But i cant do part b)
Thanks.
