Question

a+b=3-cos 4θ
a-b=4 sin 2θ
then ab is always less than or equal to p.find the value of p

Answer 1

You do I guide, deal?

Answer 2

kkk....

Answer 3

It's my order, not options

Answer 4

okkk.....

Answer 5

plus 2 equations together and solve for a
minus 2 equations together and solve for b
time a *b set it =p , done

Answer 6

* set it less than or equal to p

Answer 7

My job is done, now, you perform. YOU CAN DO IT.

Answer 8

it's cumin as a=3-cos4θ+4 sin 2θ/2
and b=3-cos 4θ-4 sin 2θ/2

Answer 9

put parentheses in, to not confuse just sin 2theta/2. got what I mean? and then, GO AHEAD

Answer 10

i didn't get what u wanted 2 say

Answer 11

\[a= \frac{3-cos4\theta + 4sin 2\theta}{2}\]the whole thing over 2. not just the last one. that's what I mean

Answer 12

YES..YYESS'

Answer 13

THEN WHAT I HAVE TO DO

Answer 14

a*b that's it

Answer 15

u mean that i have to multiply each and evry term of it and that will give me the ans

Answer 16

when you time a*b , the condition tells you that ab<=p so, you time them, and put them into the form ab<=p. that's it. or p >= ab, that's the same/
