inverse of 3cos(x)

Solution

inverse

3 cos (x)

Solution

arccos (\frac{x}{3})

Solution steps

Solve for

cos (x), y = 3 cos (x)

cos (x) = \frac{y}{3}

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

arccos (\frac{y}{3})

Substitute

y = x

arccos (\frac{x}{3})

Popular Examples

distance (1.5,-3),(1.5,-6)distance

(1.5, - 3), (1.5, - 6)

extreme f(x)=3x^3-36x-3 extreme points

f (x) = 3 x^{3} - 36 x - 3

inverse of f(x)=log_{2}(7x)inverse

f (x) = lo g_{2} (7 x)

intercepts of f(x)=4x^2-16x+14 intercepts

f (x) = 4 x^{2} - 16 x + 14

parity f(x)=(x^3)/(x^2-4)parity

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