there could be many... sin2(a/2) / cos2(a/2)
It is 1/2*m*e^2
They are terms of an expression because without an equality sign it is not an equation.
3/5 = .6
Write an algebraic expression for the verbal expression. q squared minus 2 times q
The tangent is the ratio of sine over cosine; also, in a unit circle, Y over X.
With great difficulty because in the absence of an equality sign it has no solutions but it is just some kind of algebraic expression.
The arc tangent is the recicple of the tangent which is also known as the cotangent. The tangent of π/2 is undefined, thus the cotangent would be zero.
2/128
One over A squared or A to the negative 2.
If I understand the question correctly, the answer is 99/110
There are many kinds of equivalence. Equivalent fractions are 10/40, 20/80 The equivalent decimal expression is 0.25
