This isn't my homework, it's a question

Hypotnous = H
Adjacent = Ha
Opposite =Ho

H = 15
Ho = 4
Ha = 6

What is the Theta? - How do I find the theta from the tiny number I get when I do the cosign\sin shit?

For added pleasure. How do I do reverse sin\cos\tangent- a.k.a Arc sin\cos\tan

THANKS TO YOU. Physics 2053

p.s i realize how retarded I am.

H=5
Ha=4
Ho=3

Sorry, mixed that up. i'm tired. I just need an explination on how the fuck to get theta, and how to get H\ha\ho from reverse cos\tan\etc

theta is the angle?

Hypotnous = H
Adjacent = A
Opposite =O

O/H = Sin theta
A/H = Cos theta
O/A = Tan theta

I learnt this when I was 13 I think.

H=5
A=4
O=3

3/5 = 0.6 = Sin theta

sin^-1 0.6 = theta = I can't find the button on MS calculator..

Anyway everyone knows it's 30 degrees.

Aah wtf...

sin 30 = 0.5

(sin^-1) 3/5 = 36.87

Theta sounds like boob when read in Spanish lol lol

okay...so we have the right answer after seven posts.
why is this elementary maths even here????

is a raging faggot who cares.

how do you get that?

I know the sin of fucking theta is h/o etc. that gives me a tiny fraction, how the fuck do i make it into a degree?

well on my calculator there is a sin BUTAN and above it written in yellow is sin^-1, this means if i press shift then sin it puts upon the calculator

sin^-1 on the screen, I then put the number I want to sin^-1 and press enter and out pops the answer in degrees, or radians, whichever setting you have

find out how to calculate sine yourself and do it all on paper then

lol.

>>11
is your calc set in RADIANSSSSSSSSSSSSSSSSS?

sin x = sum{ n=0->inf, (-1)^n [ x^(2n+1) ]/[ (2n+1)! ] }

x is in radians and the rest is arithmetic lol.

n is in radians, x is in decimals, sin is done using gradients

Major fail. n is an element of the naturals, {x ∈ reals : -∞<x<∞} and the value of sin(x) is expressed in radians.

value of sin x is NOT expressed in radians you retard. Its just a number.

You are expressed in degrees.

SPOILER: a value expressed in radians is dimensionless and 'just a number'
