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
It’s probably the 1st or the 4th choice but i’d say the 4th

One of the six (6) approaches to changing an undesirable behavior in toddlers is: d. all of the above.
<h3>What is behavior modification?</h3>
Behavior modification is a therapeutic process that changes any undesirable behavior in an individual, especially through the use of positive or negative consequence and biofeedback.
In Psychology, the six (6) approaches to changing an undesirable behavior in toddlers are:
- Teach them socially acceptable behaviors.
- Ignore the behavior you want toddlers to change.
- Restructure the situation.
- Pay keen attention to a behavior that is socially acceptable.
- Prevent any harmful behavior from happening.
- Redirect this energy when necessary and appropriate.
