1088 is right answer ? this question start from 5th class u don't know how to solve this problem

0Thank You

Gaurav Seth 5 years, 1 month ago

P = Rs. 800 [Amount deposited]

T = 3 years

R = 12%

S.I. = PRT/100

S.I. = 800 × 3 × 12/100

S.I. = 8 × 3 × 12

S.I. = 288

Amount recieved = Rs. 288 + Rs. 800 {Principal + Simple Interest}

Rs. 1088

Yogita Ingle 5 years, 1 month ago

The series of odd integers from 1 to 2001 is,1,3,5,7..............,2001

a=1

d=3−1=2

l=2001

a_n = a+(n−1)d

2001=1+(n−1)2

2000=2(n−1)

∴n=1001

Sn=n/2 [a+l]

=1001/2 [1+2001]

=10,02,001

Gaurav Seth 5 years, 1 month ago

Let r cos θ = –1 and r sin θ = 1

On squaring and adding, we obtain r² (cos² θ + sin² θ) = 1+ 1

⇒ r² (cos² θ + sin²θ) = 2

⇒ r² = 2 [cos²θ + sin² θ = 1]

This is the required polar form.

Gaurav Seth 5 years, 1 month ago

Prove the following identites

sec⁴x - sec²x = tan⁴x + tan²x

SOLUTION

LHS = sec⁴x - sec²x

= sec²x(sec²x - 1)

= (tan²x + 1)(tan²x) (∵ sec²x - tan²x = 1)

= tan⁴x + tan²x

=RHS

Hence proved.
