What is cube root of unity i.e. omega???
prove that :
tan [pi/4 + 1/2 cos-1 a/b] + tan[pi/4 - 1/2cos-1 a/b] = 2b/a
A school wants to award its student for the values of honesty,regularity and hard work with a total cash award of RS. 6000.Three times the award money for hardwork added to that given for honesty amounts to RS 11000.The award money given for honesty and hard work together is double the one given for regularity.Represent the above situation algebraically and find the award money for each value,using matrix method.apart from these values ,namely, honesty, regularity and hardwork, suggest one more value which the school must include for awards?
integrate 1/sinx-sin2x w.r.t x ??
If xy =ex-y show that
dy/dx=(logx)/{log(xe)}2
a letter is known to have come from either TATA NAGAR or CALCUTTA on the envelope just two consecutive letters TA are visible, what is the probability that the letter has come from 1. CALCUTTA 2. TATA NAGAR........
A card from a pack of 52 cards is lost. From the remaining cards of the pack, two cards are drawn and are found to be both diamonds. Find the probability of the lost card being a diamond.
integrate xsin-1x dx?
Using properties of determinants prove that -
(b+c)2....a2........a2
b2.....(c+a)2......b2 =2abc(a+b+c)3
c2.....c2.......(a+b)2
In this ques.. i just want to know tht after applying C1→ C1-C2, C2→ C2-C3
in this ques how can i take (a+b+c) common from C1 and C2.
if A is a square matrix of order 3, such that / adj.A / = 64 . then find / A' / .
how can we solve ; dy/dx=tan 2(x+y) or dy/dx=tan square (x+y)
1. Solve diff eqn dy/dx + y cotx = x2 cotx + 2x2. Find distance of the point (-2 , 3 , -4 ) from the line x + 2/3 = 2y +3/4 = 3z + 4/5 m,easutres II to plane 4x + 12y - 3z +1 =0
what are real numbers?
what are natural numbers?
what are integers?
what is difference between them?
tell thm in detail with examples
i have 2 question -
1)if cos-1(x/a)+cos-1(y/b)=d
prove that : x2/a2-2xy/ab-cosd+y2/b2=sin2d
2)solve tan(cos-1x)=sin(tan-1x)
3)tan-1x+tan-1y+tan-1z=pi/2
prove that xy+yz+zx =1
