SEMESTER- I
CREDIT-4
BK ID-B0947
MAX. MARKS-60
Q1.
(i) Express 7920 in radians and (7 π /12)0 in degrees
(ii) Prove that
(ii) Prove that (tanq + secq – 1)/(tanq - secq + 1) = cosq/(1- sinq ) = (1+ sinq)/ cosq
Solution:
(i)
Q2.
i. y= x^m/n being integers, n > 0 find dx/dy
ii. Differentiate log (2x + 3) from first principles
Solution.
Let y = log (2x + 3)
Let D x be a small increment in x and D y the corresponding increment in y.
Q3. Evaluate 2cosx + 3sinx/ 4 cos x + 5 sin x dx = I
Q4 Solve dy/dx = y+x-2/ y-x-4
Solution:
The given equation is:
Q5. i. If a = cos q + i sin q,0 <q < 2p prove that 1+a/1-a = I cot q/2
ii. If x+iy= √a+ib/c+id prove that (x^2+y^2) = a^2+b^2/ c^2+d^2
