The function is given to us from the trigonometry and we need to evaluate the value of a function if the initial condition is given to us.

So given the value of tangent a plus coat a is equal to 3, we need to evaluate the value of tangent of cube a plus coat of cube.

Okay, we know that a cube plus b cube is equal to a plus b into a square minus a.
00:34
Plus b square i but i don't think that that formula is good here other formula is a plus b a whole cube from this equation so that will be a cube plus b cube minus three a b b into a plus b yes that is correct a cube plus b yes this is the formula sorry in place of minus they it must be plus a plus b cube is equal to aq plus b plus 3ab into a plus yes, this is the correct.
01:17
This is the formula for a plus b whole cube.
01:23
And from here we can evaluate the value of aq plus b cube.
01:28
So that will be a plus b whole cube minus 3ab into a plus b.

In the similar way in tangent, if a is equal to tangent cube a, let me write it as tangent cube a plus quote cube that will be equal to a plus b cube it means tangent a plus coat a whole cube minus three tangent a kote into a plus a plus kote into a plus b 3 .3...
