帮帮我吧~~~
[/I]Question1: Verify the formulae in (a) and (b) for the cases (i) a=48度 and b=36度
(ii) a= -20度 and b=112度
a. cosb-cosa=2*sin[(a+b)/2]*sin[(a-b)/2]
b. tna(a+b)=[(tana+tanb)/(1-tanatanb0]

Question2: use solve () function available in symboilc math toolbox to answer this question
Solve the following equations for x:
a. sinx=cosx
b. 2*x的3次方--7*x的平方=19x-60
