Question

please help me


sin A cos B = p
sin (A-B) = q
cot A tan B = .... ?

Answer 1

sinAcosB-cosAsinB=q
sinAcosB=p
cosAsinB=p-q
cotA=cosA/sinA
tanB=sinB/cosB
cotA tanB=cosA/sinA *sinB/cosB
=cosAsinB/sinAcosB
=(p-q)/q

Answer 2

@nirmalnema so, option E is correct?

a. 1 - (q/p)
b. 1 + (q/p)
c. 1 - (p/q)
d. 1 + (p/q)
e. (p/q) - 1

Answer 3

oh wait. i dont think so

Answer 4

It looks like a typo in the last line of nirm's post
he meant
(p-q)/p
