how do i get sec70 x cos70 algebraically?
secant of an angle = hypotenuse/adjacent
cosine of an angle = adjacent/hypotenuse
What happens when you multiply
(hypotenuse/adjacent) x (adjacent/hypotenuse) ?
cosine of an angle = adjacent/hypotenuse
What happens when you multiply
(hypotenuse/adjacent) x (adjacent/hypotenuse) ?
