Write the equation for the inverse of the function y=Cos^-1(x-pi)
ser-zykov [4K]

we are given

y=cos^{-1}(x-\pi)

Since, we have to find inverse function

step-1:

Set y=f(x)

It is already there

step-2:

Switch x and y

x=cos^{-1}(y-\pi)

step-3: Solve for y

We can take cos on both sides

cos(x)=cos(cos^{-1}(y-\pi))

we can simplify it

cos(x)=y-\pi

now, we can solve for y

cos(x)+\pi=y-\pi+\pi

cos(x)+\pi=y

y=\pi +cos(x)..............Answer

Evaluate the expression if a = 3, b = 4, and c = 2. Simplify, if possible
Elanso [62]

a = 3, b = 4, and c = 2

a + b = c

3 + 4 = 2

3a + 4b = 2c
<u>        -4     -4
</u>      <u>3a</u> = <u>-6c
</u>       3       3
       a = -2

3a + 4b = 2c
<u>-3             -3
</u>       <u>4b</u> = <u>-1c</u>
        4     4

<h2>a = 2c/3 - 4b/3</h2>
