The quadratic formula is a life-saver when finding the value(s) for a variable given a complex equation. The formula itself may seem overwhelming, but the process is as simple as plugging in the numbers that are given to you from the original equation into the quadratic formula.
What are the rules for Multiplying Real Numbers? 1. Positive x Positive = Positive 2. Negative x Negative = Positive 3. Positive x Negative = Negative 4. Negative x Positive = Negative These rules apply to all Real Numbers – Whole Numbers; Decimal Numbers; Fractions
The following are the operations on Functions: a. for the sum f+h, (f+h)(x)=f(x)+h(x) b. for the difference, (f-h)(x)=f(x)-h(x) c. for the product, (f*h)(x)=f(x)*h(x) d. for the quotient, (f/h)(x)=f(x)/h(x)
Here is a problem that many students find difficulty in solving that if we are provided with two functions say one is F(X) and other is G(X) and we have to find whether F(X) >= G(X) or vice versa. the problem involves a good use of functions,Derivatives and applications of derivatives. firstly we will subtract…
Pythagorean theorem introduces the key equation to solving lengths of a right triangle’s side. (A right triangle being one that has a 90 degree angle). With the givens of two side lengths (denoted as a, b, and c, in the respective order of lengths) the equation a^2 + b^2 = c^2 can be used.
In this tutorial, I will explain how you can solve an inequality to identify the possible x values that make this inequality true. I will then describe what the actual answer means to us.
Trigonometry allows us to use ratios that are associated with any angle ABC, so we can calculate a broad range of heights without having to measure them. You will learn about three important ratios for any angle: sine (shortened to sin), cosine (cos) and tangent (tan).
