"Sound waves are waves transmitted through the air or even through liquids or solids which change the pressure of that substance enough that our ears can perceive them. The pitches of sounds we hear d ...
"A list of numbers that follows a rule is called a sequence. Sequences whose rule is the multiplication of a constant are called geometric sequences, similar to arithmetic sequences that follow a rule ...

"When introduced to vectors for the first time, learning the geometric representation of vectors can help students understand their significance and what they really mean. The geometric representation ...
"An organism's genotype is its pairing of alleles for a specific gene. Genotypes, unlike phenotypes, can be homozygous or heterozygous. If an organism is heterozygous for a gene, or possesses one of e ...
"When solving trigonometric equations, we find all the angles that make the equation true. If there is no interval given, use periodicity to show the infinite number of solutions. Two ways to visuali ...
"Genetically Modified Organisms (GMO) are organisms with altered DNA. This is often done by adding a gene from one species to another and is extremely useful in labs for drug creation, agriculture and ...
