Global warming is a gradual increase in the overall temperature of the earth's atmosphere. It generally attributes to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. In other words, global .....

To reflect the points in X-axis, P( x,y ) = P'( x,-y ) A( 4,6 ) = A'( 4,-6 ) B( 3,6 ) = B'( 3,-6 ) C( 2,5 ) = C'( 2,-5 ) D( 6,1 ) = D'( 6,-1 .....

Here, Σfx = 460 + 23a Σf = N = 20 + a Mean = ? We know,  Mean = Σfx/N             = (460 + 23a)/(20 + a)         .....

Here, height of the cylindar (h1) = 4 m. So, height of the cone (h) = 28 - 4 = 24 m. Radius of the base (r) = d/2 =  14m/2 = 7m. Let, l be the slant height of the cone then,       .....

Here, Slant height = l = 15cm Height = h = 12cm We need to find length of side of base(a). So, a =2 √(l2 .....

The co-operatives may be defined as an autonomous association. They are formed and democratically directed by people who come together to meet common economic, social, and cultural needs. Some of the major areas in which the cooperatives are .....

Here,  Length of prism = l = 15√3cm TSA = 270√3cm2 . We know,  TSA = 2 Area of base + LSA or, 270√3 = 2 ⨯√3a2 / 4 + 3a l    [ Since, LSA = perimeter of base x length] or, 270√3 .....

We have been given, the acute angle between the pair of straight lines represented by x2 + 2xysecθ + y2 = 0 is α. We have to prove that: α = 15o For this, compare  x2 + 2xy.sec15o + y2 = 0 with .....

For the first sphere, Radius ( r1 ) = x Volume ( V1 ) = ( 4  ∕  3 )π(r1)3                         = ( 4  ∕  3 )πx3 Again, For the .....

Here, 8cos3πc12-6cos⁡πc12 = 2 (4cos3πc12)- 6cos⁡πc12 = 2{ cos(3 x πc/12) + 3 cosπc/12} - 6cos πc/12   [ Since, 4cos .....

Here,  We will use the following:  [a] 2 sin x cos x = sin 2x  [b] sin(180+x) = -sin x  [c] cos(180-x) = -cos x  LHS = 16 cos 24 cos 48 cos 96 cos 168   =16 (-1) cos 12 cos 24 cos 48 cos 96    [ .....

We have to prove cosα = −1/2(k4 + 1)/k2  Taking LHS,    =  cosα .....

Here,  LHS = [ SinA/2 - √(1 + sinA)] / [ CosA/2 - √(1 + sinA)]              = [ SinA/2 - √(Sin2A/2 + cos2A/2 + 2sinA/2.cosA/2)] / .....

Here,  LHS = 1/2(cotA/2 - tanA/2) Changing cot and tan in sin & cos we get, = 1/2(cosA/2 / sinA/2 - sinA/2 / cosA/2) Taking LCM, we get = .....
