<span>let y = sec^2 ( pi x )
y' = 2 sec ( pi x ) sec( pi x ) tan ( pi x ) pi
y' = 2pi sec^2 ( pi x ) tan ( pi x )
y''= 2pi sec^2 ( pi x ) * sec^2 ( pi x ) * pi + 2pi tan ( pi x ) * 2pi sec^2 ( pi x ) tan ( pi x )
y'' = 2 pi^2 sec^4 ( pi x ) + 4 pi^2 sec^2 ( pi x ) tan^2 ( pi x )</span>
Answer:
153.94 in²
Step-by-step explanation:
Answer:D
Step-by-step explanation:
In d the x’s cancel out so y is not a function of x anymore!
Answer:
B
Step-by-step explanation:
The first term has a power and the second term doesnt have a power.
Hope it helped. Pls mark me as brainliest.
z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
