Calculus

49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2

Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2

(4/7)^x = (4/7)^-2

Therefore x = -2.

There appears to be no equation in the question: only some disjoint expressions. Expressions cannot be solved.

You can invent a number of symbols, one for each sound. However, inventing a writing that uses existing characters (for example, Latin) would be more practical, since support for such a script is widely available (for example, to type text on a computer).

Typically, the pre-requisite for calculus is algebra and trigonometry. These are usually universally required because you need these skills to actually do the mathematics of the calculus. There are a lot of identities in trigonometry that you will wish you could remember when you are working with calculus of trigonometric functions.

A complex number, equations and graphs can show electromagnetic forces-for instance two wires carrying current. A formula like (z-1)/(z+1) can show the fields around two parallel wires.

You would need to use de Moivre's theorem.

245 cubic feet.

3 x 2 x 8 = 48

(a + b)*(a - b) = a2 - ab + ab - b2 = a2 - b2

The expression is often referred to as DOTS = Difference Of Two Squares. What is special about it is that the answer contains only the squares of the two terms while the cross-products cancel out.

So (√6 + √5)*(√6 - √5) = (√6)2 - (√5)2 = 6 - 5 = 1

The above result is used to simplify surds and, in particular, to rationalise their denominators.

y=2x2 + 3x-1

To find the zeros of this equation (when y=0) set the equation = 0

0=2x2 + 3x-1

Now, you can either graph the equation in a graphing calculator and find the x intercepts (where the function crosses the x-axis and y=0) or you can factor the quadratic equation by "smiling" or reverse foiling. However, this equation cannot be easily factored. Therefore, using a graphing calculator will provide the correct answer of x= -1.780776 and x= 0.28077641

You can also use the quadratic formula

where the general form of a quadratic equation is ax2 +bx+ c=0=y

In order to use the quadratic formula, you simple plug the corresponding values into the x= equation. This will produce the same results as graphing and finding the x intercepts.

The slope is ' 5 ', so both lines MUST be parallel.

y = x - 1

Or an infinite number of other equations. You'll need to be more specific.

A scientific equation is basically a math equation. Those come in different kinds; each kind needs special techniques for solving. In the simplest case, you have to solve for a single variable; try to transform the equation so that your variable is on the left, and anything else is on the right.
