Some land masses in the Northern Hemisphere would start to warm over time-
if this ever happened, we’re all screwed :/
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
Positive outcomes of the Columbian Exchange include technological advances in farming, architecture, and weaponry.
It should be noted that the shared picture book reading was a research linked to children having communication challenges.
<h3>Importance of communication</h3>
It should be noted that fostering communication skills in children is important for their holistic development.
In this case, the meta-analysis concluded that shared picture book reading was linked to children having challenges with speeches or communication.
Therefore, the shared book reading was important for communicative development.
