The End – Collaborative Poem

He ran down the street of the suburbs. His eyes reflected the colour of the far away ocean. At that moment, the rusty door closed over the Erdrich chapel of my heart. As I watched him approach, my dreams and aspirations were nailed out a cross. Never to be resurrected. Rome wasn’t built in a […]

DNA & Protein Synthesis Model

*pictures at end* explain the structure of DNA – use the terms nucleotides, antiparallel strands and a complementary base pairing. DNA (Deoxyribonucleic acid) is shaped in a structure called a double helix, which looks like a twisted ladder. The ladder structure is made up of nucleotides that form the ladder shape. The DNA backbone is […]

3D Print Project

For this project I desinged a pulley and based my problem off one from the Systems of Masses worksheet we were given in class. I am looking for the tensions of the ropes. (images: left, orgiginal problem; right, the same problem but with my masses) I ignored possible friction and other forces that may be playing on […]

Multiplying Rational Expressions

When multiplying rational expressions it is very straight forward. You simply multiply across. Follow these simple steps: 1. Factor your fractions 2. Cancel out common factors in the pattern 3/1 +|- 1/2 +|- 2/ 3… 3. Multiply the numerators then multiply the denominators 4. You will now have your answer, add the non-permissible values (non-permissible […]

Terms to Know

– Radical/Root: √ ; ∛; etc.. – Radicand: √x – Index: ∛ (3 is the index of that radical) – Coefficient: x√y ; x(y) ;  x(n/y) – Reciprocal: the flip of a fraction; 3/4 is the reciprocal of 4/3 – Exponent: the exponent is the opposite of a radical. bn – Square Root: √ – Cube Root: ∛ – Denominator: the […]

Fractions as Bases

As you may have seen in the previous two links when a fraction is the base you treat it like any other equation (make sure there are brackets). Even if the exponents are a fraction too, or if the exponent is a negative. Just remember to keep brackets around the fraction because exponents are lazy. Example […]
