This year a question on mean value theorem and conics will come for 10 marks also a question from Boolean algebra and inverse will come for 10 marks

Active member

isn't that the pattern mentioned in the specimen paper Question

Active member

can ny1 plz solve dis question:

[b](sin^4x)*(cos^4x)
plz plz plz solve it
thnk u

Active member

s0ry but can u mention the question..?! Very Happy

Active member

i jus wrote.............ill write it again

(sin^4x)*(cos^4x)
sin to the power of 4x(4 ex) multiplied by cos to the power of 4x(4 ex)

Active member

sorry but u knw, the sine format is like "sin" followed by a variable like "sin x" ... what is that "x" here..? Your question is immersed in ambiguity.!

Active member

I think she wants to say

Math Q10

may be the question is to simplify above expression using standard trigno formulas

Active member

ya abhas thts rite..........thts my question!!!!!! Smile

Active member

yea yea..i thought same.. but i wanted the "question" ..!! to integrate or differentiate...or simplify..like that...

Active member

u may use

2sin^2 x = 1 − cos(2x)
and cos(2α) = cos2α − sin2α

to simplify the expression to some extent....but ur question seems to b incomplete as in ISc OR icse usually it is asked to prove some expression equal to other...procedure of simplification will vary according to required simplified expression

Active member

were did u get this question?

Active member

its from my math isc book................nd no no no u dont hv to prove u jus hv 2 solve it
thnx 4 da pains

Active member

you mean we have to solve it for x

then the question must be like this (sin^4x)*(cos^4x)=something

can u please tell the answer.Also tell the book which u r following.Is it M.L. Aggrawal???

Active member

Yes. Abhas is right. There must be some RHS to solve. Only an equation can be solved not an expression. This is currently an expression. What is the RHS part?

Active member

do u just need to simplify it?
