Question

@math&ing001 help in trigoo plzzzz

Answer 1

dude...can u help me in trignometry..plzz teach me how to do it

Answer 2

What do you need help with ?

Answer 3

all of trignometry..i s am weak in trigg

Answer 4

plzzz

Answer 5

I need to know where you're at in trig so I can help. Did you see sin, cos and tan, the unit circle ? Maybe just post an exercise you're having difficulty with and we can go from there.

Answer 6

i dont know how to prove l.h.s = r.h.s i tried a lot...i dont know what to do..i am even ready to give my both kidneys away if thats what is required to know how to prove as those type of quetions are asked in threefourth of the paper

Answer 7

lhs = rhs is the form of any equation, that doesn't need proof.

Answer 8

no in trignometry how do we solve themm

Answer 9

Answer 12

understanding SOH-CAH-TOA and unit circle are the most import things when you review trig

Answer 13

okieeee

Answer 14

no like iwwnat to prove l.h.s =r.h.s using identtiess

okieee

Answer 18

lemme chekkk

Answer 19

good luck!

Answer 20

i will give u an example...

Answer 21

prove that tan thitha + cot thitha =2/x^2-1

Answer 22

I don't know what you're trying to prove here since you have two diffrent variables, but if you're looking to find x as function of theta : \[\tan \theta + \cot \theta = \frac{ \sin^2 \theta + \cos^2 \theta }{ \sin \theta \cos \theta }=\frac{ 2 }{ \sin 2 \theta }=\frac{ 2 }{ \cos(2 \theta - \pi / 2)}=\frac{ 2 }{ [\sqrt{2}\cos( \theta - \pi / 4)]^{2}-1 }\]
