Why inverse trigonometric called arc function?
It is just a name invented by mathematicians.
What is 2 thetasin theta equals cos theta?
It is a simple trigonometric equation. However, without information on whether the angles are measures in degrees or radians, and with no domain for theta, the equation cannot be solved.
How do you calculate trigonometric ratios of obtuse angles?
If ø is an obtuse angle then (180 - ø) is an acute angle and: sin ø = sin (180 - ø) cos ø = -cos (180 - ø) tan ø = -tan (180 - ø)
Which trigonometric functions have asymptotes?
tangent, cosecants, secant, cotangent.
What is unary?
It refers to one.A binary function (binary = 2) takes two numbers as input and gives the result (output) as a single number. Thus, addition is a binary function. Some functions, like squaring or trigonometric functions are examples of unary functions. These have only one input.
