I need some help in a problem from Calculus 1 class:
Find the lim sin3t + 4t
tsect
when t approaches 0.
To learn how to format using only text, try here. My guess as to your meaning, using LaTeX formatting, is as follows:
. . . . .
A good way to start might be to split the addition into two parts, also converting the reciprocal of the secant into a cosine:
. . . . .
You learned an important trig limit, probably when you were learning trig derivatives:
. . . . .
With this in mind, restate the limit as:
. . . . .
The cosine can be simply evaluated, and the sine fraction is the limit they gave you earlier.
