tan (22 5^{\circ} - x)

- \frac{sin ( x ) - cos ( x )}{cos ( x ) + sin ( x )}

Solution steps

tan (22 5^{\circ} - x)

Rewrite using trig identities

= - \frac{sin ( x ) - cos ( x )}{cos ( x ) + sin ( x )}

161.8 sin (10.5 x + 1.3) + 655

cos (2 x - π)

sin (x) e^{l n (1 - c o s^{2} (x))}

4 sin (3 θ - \frac{π}{3}) + 1

cos (\frac{π}{20} (- x) + 0.25)

What is tan(225-x) ?
The solution to tan(225-x) is -(sin(x)-cos(x))/(cos(x)+sin(x))
