inverse of cos(90)

Solution

inverse

cos (9 0^{\circ})

Solution

None

Solution steps

Convert

90

degrees to radians:

\frac{π}{2}

cos (\frac{π}{2})

cos (a) = b \Rightarrow a = arccos (b)

\frac{π}{2} = arccos (y)

Solve for

x, \frac{π}{2} = arccos (y)

Since the function is a constant function it has no inverse function

None

Popular Examples

f (x) = \frac{2 x + 3}{3 x - 4}

inverse of f(x)= 5/7 x+4 inverse

f (x) = \frac{5}{7} x + 4

inverse of f(x)=3(e/2)+e^{2x}inverse

f (x) = 3 (\frac{e}{2}) + e^{2 x}

inverse of y=-3x^2+100x+1 inverse

y = - 3 x^{2} + 100 x + 1

inverse of f(x)=19x^2-17 inverse

f (x) = 19 x^{2} - 17
