can any one help me to get an easy way to solve the trig of angles

Question

anonymous · Answer

can you give me an example of the question you're asking for?

hba · Answer

sin(30)=_____ @dpaInc

anonymous · Answer

ok... so you're referring to the trigonometric values of common angles... is that correct?

if yes, then it's best to just remember unit circle... but that too, might be too much (especially for me) 
so all i do is remember the sides of a 30-60-90 and 45-45-90 triangles.

for your example, sin(30 degrees) = 1/2, because in a 30-60-90 triangle, the shortest side is 1/2 of the hypotenuse.

n what about values like sin(1)

anonymous · Answer

here is the unit circle... look at page 3... http://tutorial.math.lamar.edu/pdf/Trig_Cheat_Sheet.pdf

hba · Answer

thanks

anonymous · Answer

is that 1 degree or 1 radian?

hba · Answer

none

hba · Answer

i think its 1 degree

anonymous · Answer

either way, 1 degree or 1 radian is not a common angle so it's best to just use a calculator to find sin(1)

hba · Answer

and if i am nt allowed to use a calculator then

anonymous · Answer

oh yeah... do you know how to use trig tables?

hba · Answer

thats also not allowed we have to learn it

anonymous · Answer

well then... i'd like to see someone show how to get the value of sin(1) without calculator or trig tables....

hba · Answer

rote learn it bro

anonymous · Answer

ok... can you show me how to do it?

anonymous · Answer

i'd like to learn....

hba · Answer

come to pakistan ill teach u

anonymous · Answer

yeah.... right....

hba · Answer

:D

anonymous · Answer

you might as well be asking find  approximation for $\sqrt5 $ to the nearest 10 decimal places..... so the answer is "who cares?"
