Part of the graph of y = 2 sin x + 5 cos x is shownExpress y = 2 sin x + 5 cos x in the form k sin (x + a) where k > 0 and 0 a 360b) Find the coordinates of the minimum turning point P.Expand ksin(x + a):Equate coefficients:Square and addDividing:Put together:Minimum when:P has coords.sin + , cos +

Expand k sin(x - a):Equate coefficients:Square and addDividing:Put together:Sketch GraphWrite sin x - cos x in the form k sin (x - a) stating the values of k and a where k > 0 and 0 a 2b) Sketch the graph of sin x - cos x for 0 a 2 showing clearly the graphs maximum and minimum values and where it cuts the x-axis and the y-axis.a is in 1st quadrant(sin and cos are +)
