Answer 8

Do you know how to define a trigonometric function in terms of the sides of a right triangle ??

Answer 9

i don't :/

Answer 10

Let x be an angle of a right angled triangle (other than 90)

Definition
Hypotenuse (H) - longest side
Base (B) - side between and x and right angle
Perpendicular (P) - the third side

Trigonometric functions -
sin x = P / H
cos x = B / H
tan x = P / B

csc x = 1/ (sin x)
sec x = 1/(cos x)
cot x = 1/(tan x)

Answer 11

i always draw my triangle and make sin csc bottom then other side is sec and cos and hypothesis is tan and cot ... keeping these together in mind comes in handy also knowing and memorizing the 3 different triangles(30, 60, and 90 degree)helps a lot in working with trig problems
