sin ( 90 * - α)
____________
cos ( 90 * - α)
sin ( 90 * - α) = cosα
cos ( 90 * - α) = sinα Tak
b)
(1 - cos²α)/ sinα = sin²α/sinα = sinα
cos (90 * - α) = sinα Tak
c)
(sin²α + cos²α)/tg ( 90 * - α) = 1/ctgα = tgα Tak
d)
sin a • sin ( 90 * - α)
__________________ = cos α
cos (90 * - α)
sinα*cosα/sinα = cosα Tak
