inverse of 4cos(x)+1

Solution

inverse

4 cos (x) + 1

Solution

arccos (\frac{x - 1}{4})

Solution steps

Solve for

cos (x), y = 4 cos (x) + 1

cos (x) = \frac{y - 1}{4}

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

arccos (\frac{y - 1}{4})

Substitute

y = x

arccos (\frac{x - 1}{4})

Popular Examples

extreme f(x)=3x-x^2 extreme points

f (x) = 3 x - x^{2}

slope of 2x+4y=8 slope

2 x + 4 y = 8

inverse of f(x)=-6x-1 inverse

f (x) = - 6 x - 1

intercepts of f(x)=sqrt(x^2-9)intercepts

f (x) = x^{2} - 9

domain of f(x)=-x+5 domain

f (x) = - x + 5
