simplify sin(arctan(x/z))

simplify

sin (arctan (\frac{x}{z}))

\frac{x z ^{2} + x ^{2}}{z ^{2} + x ^{2}}

Solution steps

sin (arctan (\frac{x}{z}))

Use the following identity:

sin (arctan (x)) = \frac{x 1 + x ^{2}}{1 + x ^{2}}

= \frac{( \frac{x}{z} ) 1 + ( \frac{x}{z} ) ^{2}}{1 + ( \frac{x}{z} ) ^{2}}

Simplify

= \frac{x z ^{2} + x ^{2}}{z ^{2} + x ^{2}}

f (x) 5 sin (x + π)

cot^{2} (- csc^{2} (x))

- 2 cos (x + π) - 7

sin (36 0^{\circ} - α)

tan (18 0^{\circ} - b)
