You might have learnt about Thermal expansion. When a certain metal is heated, it expands. So, iron rims are also heated before putting them on the wheels of bullock carts, because the rims are metallic, when the rims are heated they expands and .....

There are three half angle formulas for the tangent. One of them gives us

When the answer is given by a square root, one needs to dtermine the sign by checking out the slope of the line. In this case, a .....

To solve this, we have to use formula of compound angle and multiple angle. So, lets start from LHS. 4 cosA.cos(60 - A).cos(60 + A)  = 4 cos A [ (cos(60) cos(A) + sin(60) sin A) ( cos(60) cos A - sin(60) sin A) ]  = 4 cos A [ (1/2) .....

To prove this we have to using idea of compound angle and multiple angle. Take LHS and simplify it. =√3csc20° - sec20°  = √3(1/sin20°) - 1/cos20°  = (√3cos20° - .....

The general equation of a circle is (x-h)^2 +(y-k)^2 = r^2, where (h,k) are the coordinates of the center of the circle and r the radius of the circle. So there are three unknowns h,k and r and so we need 3 equations. So the equations .....
