simplify-cot(x/2+pi/4)

simplify

- cot (\frac{x}{2} + \frac{π}{4})

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

Solution steps

- cot (\frac{x}{2} + \frac{π}{4})

Rewrite using trig identities

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

cos (\frac{π}{2} - v)

a r cos (\frac{- 1}{2})

sin (nπ) + sin (- nπ)

a r cot (\frac{- 3}{4})

(v cos (wt - \frac{π}{4}))^{2}
