Question: Prove each identity. (a) arcsin(x) = arcsin x (b) arctan(x) = arctan x (c) arctan x + arctan 1 / x = / 2,

Prove each identity.
(a) arcsin(−x) = −arcsin x
(b) arctan(−x) = −arctan x
(c) arctan x + arctan 1 / x = π / 2, x > 0
(d) arcsin x + arccos x = π / 2
(e) arcsin x = arctan x / √1 - x2
