Question

Can anyone help me with Right Triangle Trigonometry?

Answer 1

Sure, what are the questions ?

Answer 2

me what is the problem

Answer 3

I'm having trouble understanding Cos and sin. @JonnyVonny @alawi1234

Answer 4

No problem. When dealing with triangles of any sort, we use trigonometry to find the lengths of any side of a triangle, or any angle, given the appropriate information. In the introduction into trigonometry,they should have taught you the Pythagorean theorem. From this, we know that we can find any missing length of a triangle, so long as we know 2 side lengths, and that it is a right triangle. Knowing only this IS NOT very efficient; if you're only given the value of one side, and a degree, what do? QQ?
No. Just know the trig functions; sine, cosine, and tangent.

Answer 5

To easily remember what sine, cosine, and tangent can actually find for you, you may remember "SOH-CAH-TOA". This translates into:
sin=opposite/hypotenuse
cos=adjacent/hypotenuse
tan=opposite/adjacent

Answer 6

Tell me if you're with me so far.

Answer 7

More so, after every trig name, there is a theta (and all theta is, is the degree that you're given), so:\[\sin \theta = opposite/hypotenuse \]\[\cos \theta = adjacent/hypotenuse\]\[\tan \theta =opposite/adjacent \]
As I said before, we may only use certain trig functions when appropriate; depending on the given information, we are able to only work what with they give us.
