Inverse Trig Functions Worksheet Inverse Cosine Calculator Inverse Sine Calculator The inversetrigonometric functions(sin-1, cos-1, and tan-1) allow you to find the measure of ananglein aright triangle. All that you need to know are any two sides as well as how to useSOHCAHTOA. ...
sin(θ) = Opposite / HypotenuseAnd Inverse Sine is :sin-1 (Opposite / Hypotenuse) = θWhat About "cos" and "tan" ... ?Exactly the same idea, but different side ratios.CosineThe Cosine of angle θ is:cos(θ) = Adjacent / HypotenuseAnd Inverse Cosine is :...
The derivatives of inverse trig functions can be written in alternative notation as follows:d/dx (sin-1x) = 1/√1-x² d/dx(cos-1x) = -1/√1-x² d/dx(tan-1x) = 1/(1+x²) d/dx(csc-1x) = -1/(|x|√x²-1) d/dx(sec-1x) = 1/(|x|√x²-1) d/dx(cot...

The integrals of inverse trig functions are tabulated below:Inverse Trig FunctionIntegral ∫ sin-1x dx x sin-1x + √(1 - x²) + C ∫ cos-1x dx x cos-1x - √(1 - x²) + C ∫ tan-1x dx x tan-1x - (1/2) ln |1 + x²| + C ∫ csc-1x dx x csc-1x + ...
arcsin(x) = sin-1(x) arccos(x) = cos-1(x) arctan(x) = tan-1(x) As stated at the left, the exponent of -1 denotes "inverse". It does not mean 1/sinx, such asx-1= 1/x. y= arcsin(x) = sin-1(x) solves the equationx= sin(y). ...

Your calculator will give you an answer of around 55°, but that’s just one out of infinitely many. You know from equation 22 that sin(180° − x) = sin x, and since 180° − 55° = 125°, sin 125° = sin 55. But all the trig functions are periodic, repeating every 360...
