Casio FX-115ES Scientific Calculator "calculating inverse tan" Questions

...the inverse of cot(-4) well there is no cot function on this calculator so you have to use the identity. Cot is 1/tan so the inverse cot is 1/inverse tan which is on this calculator so =

TAN] have inverse functions arc-sine, arc-cosine, and arc-tangent which are also implemented on scientific calculators. To access the inverse trigonometric functions you use the sequences [SHIFT][SIN]

inverse of tan cos sin The inverse trigonometric function share each the same physical key with its direct function. The inverse trigonometric functions are accessed with the [SHIFT] key [SHIFT] [SIN]
