Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution
Answer:
get some crickets or sum and lure them in
MUCH lower. And that is the truth! We have done several of them here and CLEP exams cost about $80 for the exam and maybe $40 for the study guide. Compare that with a $500 class. MUCH lower.
The answer is none of the above, i dont know how but i was just asked the same question and got it wrong so yeah lol
Hurricanes are formed in tropical places. And hurricanes and thunderstorms are two totally different things! And so the best answer is C. I hope this helped u!
