2^sin x + 2^cos x......where ^ is symbol for 'to the power'
a..certainly I can I can use differential and..but like if I take the 2 numbers in A.P.....then by using A.P.>GP...
so I am able to get the minimum value...but is there an algebraic way to solve it...not using calculus...I am rather uncomfortable with calculus if it goes complex.
