Trigonometry

You could try the series sin(x) = 1 - x/1! + x^3/3! - x^5/5! + ...

but you would soon need a calculator. And if you're using a calculator you may as well use it to find the sine.

We call it equilateral.

A quotient is a binary operation. That means, you can calculate the quotient of two numbers. There cannot be a quotient of only one number.

sin 300 = 1/2

If you changed the angles, the hexagon would become irregular. The angles can be changed, but not to form another regular hexagon. That is the rule. The total angles will be 720 degrees.

You are looking for this answer because your dumb its true.

There are more than two but the two most common ones are plane trig and spherical trig.

With n lines, the maximum number is n*(n-1)/2. The minimum is 0.

Exponents did not change math, per se, math has always been the same. But the use of them has changed the way math is done. It has allowed mathematic formulas to be shortened and simplified.

Opposite of differentiation. Given the rate of change of something (for example, speed [which is rate of change of position] ) which might vary according to some formula, then integration is a way of calculating the total distance after a specified interval.

It is a real number because for example water freezes at 0 degrees Centigrade

12*tan(24 deg) = 5.3427, approx.

a girl 1.2m tall is 25m away from a tower 18m high what is the angle of elevation of the top of the tower from her eyes?

tan(b) = x/sqrt(y^2-x^2)

A step ladder is not something that you calculate!

Infinitely many.For a start: t, tt, ttt, tttt, and so on until (?) you have infinitely many ts.

If it has an hypotenuse then it must be a right angle triangle then by using Pythagoras' theorem its hypotenuse is 2.86 cm rounded and by using trigonometry its smallest angle is 35.02 degrees rounded.

yes. there are certain formulae for solving them. dont remember

uhhhh
