Y = sin(x)
Determine (the 123rd derivative of y)

-cos(x)

Step-by-step explanation:

y¹ = cos(x)

y² = -sin(x)

y³ = -cos(x)

y⁴ = sin(x)

Every 4th derivative is sin(x)

123 = 4(30) + 3

y¹²⁰ = sin(x)

y¹²¹ = cos(x)

y¹²² = -sin(x)

y¹²³ = -cos(x)

Step-by-step explanation:

Step 1:  Find the derivative of the equation four times

Therefore, every for derivatives that we do, we will get back to sin(x).

Step 2:  Find the 123rd derivative of the equation

We are going to have to repeat this cycle for 30 rounds and then, we will have sin(x) as the 120 derivative.  Now, we can do it three more times to get the 123rd derivative.

 The 123rd derivative of y is -cos(x)

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
