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