Write in terms of the cofunction of a complementary angle sec(62 degrees)

Answer 1

Since the sine function is the cofunction of the complementary angle to cosine, we know that:

cos(62 degrees) = sin(90 degrees - 62 degrees)

Cosine is the reciprocal of secant, so we can rewrite the equation as:

1/sec(62 degrees) = sin(90 degrees - 62 degrees) = sin(28 degrees)

Therefore,

sec(62 degrees) = 1/sin(28 degrees)
