simplify 2tan(x+pi/2)

simplify

2 tan (x + \frac{π}{2})

- 2 cot (x)

Solution steps

2 tan (x + \frac{π}{2})

Rewrite using trig identities

= 2 (- \frac{cos ( x )}{sin ( x )})

Simplify

2 (- \frac{cos ( x )}{sin ( x )}) : - \frac{2 cos ( x )}{sin ( x )}

= - \frac{2 cos ( x )}{sin ( x )}

Rewrite using trig identities

= - 2 cot (x)

cos (\frac{3 π}{2} + a)

25 - 25 sin^{2} (x)

cos (3 0^{\circ} - θ)

tan (0 + x)

cos (- cos (x))
