(cos2 25+cos2 65) here your answer
using formula sin-thida=cos thida
(cos2 (90-65)+cos2 65)
cos 90-thida is equal to sin-thida
sin2 65+cos2 65=1 because sin square thida plus cos square thida is equal to the one
sec 90 minus thida is equal to the cosec thida
tan90 minus thida is equal to is equal to the cot thida
