Question

What is the value of `csc 40°`?

Answer 1

approximately `1.5557`

Explanation:

Note that:

`color(red)(|barul(color(white)(a/a)color(black)(csc(theta)=1/sin(theta))color(white)(a/a)|))`

Thus:

`csc(40˚)=1/(sin(40˚))`

Very simply, this can be plugged into a calculator (make sure you're in degree mode, not radian mode):

`1/(sin(40˚))approx1.5557`
