## Homework Statement

I am trying to find out how to solve for x without a calculator.

Basically where [tex] tan({x}) [/tex] and [tex]sqrt{2}*cos{x}[/tex] intersect.

## Homework Equations

Find [tex]x[/tex] in the range of [tex]0 \le {x} \le \frac {pi}{2}[/tex]

## The Attempt at a Solution

I couldn't find out how to solve this without a calculator.

I tried fooling around with the trigometric properties like the double argument and pythagorean, but I still couldn't find out.

My teacher doesn't know either. lol.

The answer by looking at it graphically is [tex]\frac {pi}{4}[/tex]
