Question

Verify the identity.

cot2x + csc2x = 2csc2x - 1

Answer 1

yeah i'm on it

Answer 2

csc is cosec right??

Answer 3

i dont know anything about this @rajat97

Answer 4

okay no problem

Answer 5

i'm not getting the rhs correct
would you please check the identity again???
or if it is to check it , then it is wrong

Answer 6

i think so

Answer 7

Verify the identity.

cot^2x + csc^2x = 2csc^2x - 1

Answer 8

@rajat97 sory my mistake it is ^2 not just 2

Answer 9

okay now i'm on it
and its okay

Answer 10

okay
here csc x is cosecx
we have an identity
cot^2x +1 =cosec^2x
here , lhs=cot^2x+cosec^2x
and we can write it as 1+cosec^2x +cosec^2x(from the identity)
so cot^2x+cosec^x=1+2cosec^2x

Answer 12

yes i got it @rajat97

Answer 13

:)

Answer 14

any more questions

Answer 15

Verify the identity.
1 + sec^2xsin^2x = sec^2x

Answer 16

we can write sec^2x=1/cos^2x
so sec^2xsin^x=sin^2x/cos^2x=tan^2x
and by an identity, 1+tan^2x=sec^2x

Answer 17

how should i write it on the paper

Answer 18

i'll upload a photo

Answer 19

ok

Answer 20

wait for a few moments please

Answer 21

ok

Answer 22

not too clear but i think you can zoom

Answer 23

Verify the identity.
cos(α - β) - cos(α + β) = 2 sin α sin β

Answer 24

can you write the same way you did with the last one...

Answer 25

IT IS VERY CLEAR ..

Answer 26

i'm on it

Answer 27

The following data represents the normal monthly precipitation for a certain city.
