Question

Could someone help me learn better about SOH-CAH-TOA, Sectants,Cosectants and cotangents along with special triangles (45-45-90 &30-60-90

Answer 1

do u know what SOH CAH TOA MEANS

Answer 2

Sin, Cosine and tangent.

Answer 4

will this help http://openstudy.com/study#/updates/4f9be55ee4b000ae9ed11844

Answer 5

try and look at it..then tell me if it helps (even a bit) or not

Answer 6

Well my big problem was the Sectant, cosectant and cotangent.

Answer 7

sec.you just take the reciprocal of cosine

csc..take the reciprocal of sin

cot..take the reciprocal of tan

Answer 8

you are familiar with reciprocals yes?

Answer 9

DID u the slides

Answer 10

Yeah flipped fraction the reverse.

Answer 11

exactly

Answer 12

So all it is, is the opposite?

Answer 13

yup

Answer 14

Now the special triangles?

Answer 15

\[\sec 30 = \frac{1}{\cos 30}\]
\[\csc 30 = \frac{1}{\sin 30}\]
\[\cot 30 = \frac{1}{\tan 30}\]
and so on

Answer 16

special triangles? you mean 30-60-90 and 45-45-90?

Answer 17

Mhm.

Answer 18

in 30-60-90 what you need to know is

1) the leg opposite of the 30 degree angle is 1/2 of the hypotenuse
2) the leg opposite of the 60 degree angle is 1/2 of the hypotenuse x \(\sqrt 3\)
3) the hypotenuse is twice the length of the side opposite 30 degree angle

i.e.

got that?
