Answer 1

@nirmalnema

Answer 2

= cos5 cos - sin5 sin
is this correct so far ?

Answer 3

@UnkleRhaukus

Answer 4

@ganeshie8

Answer 5

@paki

Answer 6

= cos5 cos - sin5 sin ==== > how you obtained this

Answer 7

yes @paki

Answer 8

@eric_d can you simplify it further

Answer 9

see this formula.you will get direct answer

Answer 10

cos(a-b) = cosa cosb + sina sinb

Answer 11

cos(5θ) cos(θ) + sin(5θ) sin(θ)
= cos(5θ - θ)
= cos(4θ)

Answer 12

the given answer is -tan 3 theta

Answer 13

@dg2 there is division not addition

Answer 14

cos(5θ - θ)/sin(5θ - θ) is this the question

Answer 15

(cos5theta-cos theta)/ (sin5theta-sin theta)

Answer 16

same ya so we get cos 4θ/sin4θ

Answer 17

how do u get that

Answer 18

take cos as common in numerator and sin as common in denominator?

Answer 19

that a rubbish thing u cant do that

Answer 20

@nirmalnema be cool.. .try to lecture them regarding this please... :)

Answer 21

if i made a blunder i am sorry @nirmalnema

Answer 22

It's alrite........
Thanks everybody...
@MM is guiding me..

Answer 23

@dg2 its ok no problem.!!
but always remember this its wrong you cant take it out common like that

Answer 24

multiply cos 3θ in numertor and denominator first
