Find tangent line at x=\pi , given: y=3sin^(2 )((x)/(2))

Mathematics
1 answer:
Luba_88 [7]3 years ago
5 0
The slope of the tangent line to y=3\sin^2\dfrac x2 is

y'(x)=3\sin\dfrac x2\cos\dfrac x2=\dfrac32\sin x\implies y'(\pi)=0

which means the tangent line at this point is horizontal.

Because the tangent line passes through

y(\pi)=3\sin^2\dfrac\pi2=3

the tangent line has equation y=3.

What is the solution for the equation 14.8 equals n -0.3
vodomira [7]

Hello there!

14.8=n-0.3

Answer:

\boxed{n=15.1=15.0}

You can also round up to the nearest tenths is 15.1 to 15.0 and its going to be stay.

Step-by-step explanation:

First you had to switch sides of equation form.

n-0.3=14.8

Then you add by 0.3 from both sides of equation form.

n-0.3+0.3=14.8+0.3

And finally, simplify by equation. You can also cross out by -0.3+0.3 and it gave us equal to zero. Then you add 14.8+0.3 and it equal to 15.1. You had to used their variable and its should be the right answer.

n=15.1

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
