(1)the value of \pi ^{c} (pi to the power c) is.....................
(2)sin² 28° + sin² 62° = .......................
pls reply ssssssssssssssssooooooooooooooooooooonnnnnnnnnnn!!!!!!!
tmr i hav my board xam
TPS:
what is c?
even i was confused it was given in model q p.is it wrong?
have you written the question correctly?
s it is correct
pls reply
i don't think it is correct..there should be something else given
k but 2nd one????
i too think the first question is wrong

(2) sin² 28° + sin² 62°
sin 62° = cos(90 - 62)° = cos 28°
sin² 28° + sin² 62°
= sin² 28° + cos² 28°
= 1
(use the identity: sin² β + cos² β = 1)
sin 62° = cos(90 - 62)° = cos 28°
sin² 28° + sin² 62°
= sin² 28° + cos² 28°
= 1
(use the identity: sin² β + cos² β = 1)

(2) sin28 = sin(90-62) = cos62
Substitute the value
sin² 28° + sin² 62°
=cos²62 + sin²62
we know that sin²Ф + cos²Ф = 1
Hence'
cos²62 + sin²62 = 1
sin² 28° + sin² 62° = 1
Substitute the value
sin² 28° + sin² 62°
=cos²62 + sin²62
we know that sin²Ф + cos²Ф = 1
Hence'
cos²62 + sin²62 = 1
sin² 28° + sin² 62° = 1
thnks
mention not!!
but how come you have got so many points
by answering questions :)
not like that,i hav nly 110 points
you can also score more points.But the only thing is that you should answer questions.and i loggin brainly everyday.so i get more points :)
thank you:)
but will u get time to read?or doing all brainly?
