## anonymous one year ago Solve the equation for x: sinx=cosx I tried dividing both sides by cosx and using one of the quotient identities but I got the wrong answer

1. lucaz

use the unit circle

2. IrishBoy123

if $$sinx=cosx$$, we can conclude something about x |dw:1439506688997:dw|

3. IrishBoy123

$$\large \sin{x} = \frac{o}{h}$$ $$\large \cos{x} = \frac{a}{h}$$

4. IrishBoy123

|dw:1439507142520:dw|

I keep getting pi over 4 and the answer is pi/6 + 2pi/3 n (n=any term because there isn't a limit)
