To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent. The only inverse function below in which x may be 0, is arccot x. arccot 0 = π /2. Again, we restrict the values of y to those angles that have the smallest absolute value. The inverse relations. If we put. f(x) = sin x. and. g(x) = arcsin x, then according to the definition of inverse functions (Topic 19 of Precalculus): f (g(x)) = x and g (f ...

Calculator Use This calculator will find the inverse trigonometric values for principal values in the ranges listed in the table. You can view the ranges in the Inverse Trigonometric Function Graphs. Inverse Trig Function Ranges The exsecant (exsec, exs) and excosecant (excosec, excsc, exc) are trigonometric functions defined in terms of the secant and cosecant functions. They used to be important in fields such as surveying, railway engineering, civil engineering, astronomy, and spherical trigonometry and could help improve accuracy, but are rarely used today except to simplify some calculations. Some calculators have a button labeled “2nd.” Others use alternate colors — usually yellow or green — to denote the second use of the button. And even when you find the inverse functions, you’ll notice that they’re only for the three primary trig functions. The calculator doesn’t show any way to access cosecant, secant, or cotangent. The calculator will find the inverse sine of the given value in radians and degrees. The inverse sine `y=sin^(-1)(x)` or `y=asin(x)` or `y=arcsin(x)` is such a function that `sin(y)=x`. The domain of the inverse sine is `[-1,1]`, the range is `[-pi/2,pi/2]`. It is an odd function. For graph, see graphing calculator. The Ugly Side of Inverse Calculator . Otherwise, you might find some weird outcomes. However there are numerous cases where this isn't the scenario, and this is the point where the student faces more of a challenge.
