Learning on Youtube is easier then learning in a class room. Thank you so much! Maybe i can escape this class with a D (passing) after all. Lol!

You got this answer because you had your calculator in radian mode. When doing trigonometry, it is always important to know which mode your calculator is in (radians or degrees). For this problem, you should use degrees.

SOH CAH TOA!

thx for ur help
-
in order to remember how to find sin/cos/tan i usually use SOHCAHTOA (: and then for csc, sec, and cot their just flipped. this was great review for my final tomorrow, so thank you

For your example problem, would you also be able to use the Pythagorean theorem?
otopilas700 7 months ago
@otopilas700 To use the Pythagorean Theorem you have to know the lengths of two sides of a right triangle in order to find the length of the third side. In this problem, we initially only know the length of one side. After finding that side using trig, we could then find the third side by the Pythagorean Theorem.

has anyone noticed that the length he got for the hypotenuse was less than the length of the adjacent? isnt the hypotenuse suppose to have the longest side?

@707skylitchoco 23.7 > 10 ... ? Maybe watch again :) I saw your guitar cover by the way. Not bad! I play some guitar also.
