Question

Find the value of sec(theta°)cos(theta°) for the following values of theta.
c. theta = 330

Answer 1

sec(330°)cos(330°) = 1

Explanation:

given data

theta = 330

to find out

sec(theta°)cos(theta°)

solution

we have given equation

sec(theta°)cos(theta°) ......................1

so put here value of theta in equation 1

= sec(330°)cos(330°) ..............2

we know sec(330°) =
`(1)/(cos330)`

so from equation 2

=
`(1)/(cos330)` cos(330°)

= 1

so here sec(330°)cos(330°) = 1
