tan (theta x theta) : must square the value of the angle, theta, before applying the trig function, tangent.
tan2(theta) + 5*tan(theta) = 0 => tan(theta)*[tan(theta) + 5] = 0=> tan(theta) = 0 or tan(theta) = -5If tan(theta) = 0 then tan(theta) + cot(theta) is not defined.If tan(theta) = -5 then tan(theta) + cot(theta) = -5 - 1/5 = -5.2
Tan theta is a function of the number theta.
It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
Tan^2
It is 100*tan(theta).
Yes, it is.
Since sin(theta) = 1/cosec(theta) the first two terms simply camcel out and you are left with 1 divided by tan(theta), which is cot(theta).

-2(cot2theta)
Remember that tan = sin/cos. So your expression is sin/cos times cos. That's sin(theta).
