simplify

- cot (18 0^{\circ} - x)

cot (x)

Solution steps

- cot (18 0^{\circ} - x)

Rewrite using trig identities

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

Apply rule

- (- a) = a

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

Rewrite using trig identities

= cot (x)

tan (arccos (\frac{x}{5}))

1 + (tan (x))^{2}

sin (- x) + sin (x)

cos (72 0^{\circ} + x)

cot (\frac{π}{2} - x) cos (x)
