Hi Khanak. Yes you can take PCB in 11th and get admission in integrated MSC course but it depends on the specialization you are taking . For example, after taking PCB, you can go for courses like  B.Sc. in Microbiology, Biochemistry, Biotechnology, Psychology, etc. which do not require math but

Hi Khusboo,

I believe you've missed the squares in your question. The correct question would have been ==> 9cosec²A - 9cot²A is equal to? [If you want a numeric answer]

Solution:

9cosec²A - 9cot²A

= 9(cosec²A - cot²A)

= 9 × 1 [Since cosec²A - cot²A = 1]

= 9

Dear Student,

aCosA = 1

This implies Cos A = 1/a......................................................................(Equation1)

bSinA = 1

This implies Sin A = 1/b .........................................................................(Equation 2)

Tan A  = Sin A/Cos A..............................................................................(Equation 3)

Therefore ,

From (1),(2) &  (3)

we get,

Tan A = (1/b)/(1/a)

TanA = a/b

Hi Keshav,

Hope you are doing well.
