1)Prove that (cos(x)-sin(x))(cos(2x)-sin(2x)=cos(x)-sin(3x)
2)The graph of the function f is the graph of function g(x)=a sin(x-pi/3) translated vertically by 2.Also f(pi/2)=1.Find the formula in terms of x for function f.
3)Linda measures the angle of elevation from a point on the ground to the top of the tree and find it to be 35°.She then walks 20metres towards the tree & finds finds the angle of elevation from this new point to the tree to be 45°.Find the height of the tree.(Round answer to three significant figures)
4)Find all angles of a triangle with sides 9,12,&15.
5)Find the exact values of cos(13pi/12)
