Verify that pi/3 and x=30degrees is equal to this equation. LHS=RHS
(secx+tanx)cosx-1 = sinx
***
x=30˚
(secx+tanx)cosx-1 = sinx
(1/cosx)+tanx)cosx-1=sinx
(2/√3+1/√3)(√3/2)-1=1/2
1+(1/2)-1=1/2
1/2=1/2
verified:LHS=RHS
..
x=π/3
(secx+tanx)cosx-1 = sinx
(1/cosx)+tanx)cosx-1=sinx
(2+√3)(1/2)-1=√3/2
1+√3/2-1=√3/2
√3/2=√3/2
verified:LHS=RHS
