It's almost "e day"!!! (2.7) Get ready for Friday with this blog post: "Exploring e" gives some ideas for learning about the Euler number in math class. #MTBoS #iTeachMath #MathSky #MathsToday #calculus #precalculus karendcampe.wordpress.com….

Exploring e

Image credit: MathIsFun.com Sarah (@mathequalslove)1 tells me that today, February 7, is “e day” because the date is 2-7 in month-day order. You might recall that e is a number sometimes called the…

Happy Saturday! Let's do some quick #ProblemSolving using #TryMathLive #TryMathsLive from the February Calendar of Problems. Here is Feb 9, a great one to remind Ss of exponent laws & common base strategy. #Algebra2 #Precalculus #MTBoS #iTeachMath #MathSky

Given 2^x = 8^(y+1) and 9^y = 3^(x-9),
find the value of x+y.

Reaching for messy derivative quotient rules the second you see 5 sin θ - 12 cos θ + 17 in the denominator is a classic time trap. Instead of grinding through calculus, rewrite the wave using the R-formula where R equals… #trigonometry #precalculus #studytips #funny #animation #tomfamily #SoviAI

Dumping calculus derivatives onto 7 sin θ + 24 cos θ - 11 is an easy trap when the R-method solves it in seconds. Instead of grinding through product rules and setting derivatives to zero, rewrite the linear combination as… #trigonometry #precalculus #studytips #funny #animation #tomfamily #SoviAI

Reaching straight for calculus on f(x) = 5 sin(2x) - 12 cos(2x) + 7 will only burn precious time taking messy derivatives and setting them to zero. The smarter fix is using harmonic addition: treat the coefficients 5 and… #trigonometry #precalculus #mathhacks #funny #animation #tomfamily #SoviAI

That split second when you see 7 sin x + 24 cos x and immediately reach for derivative rules—only to watch sqrt(7² + 24²) clean up the entire problem in three neat blue handwritten steps. Using the R-formula transforms the… #trigonometry #precalculus #studytips #funny #animation #tomfamily #SoviAI

Skipping a massive 9th-degree binomial expansion starts with converting (1 + i√3) directly into polar form on lined paper. First, grab the magnitude r = 2 and argument θ = π/3. Next, let De Moivre take over by raising… #complexnumbers #precalculus #studytips #funny #animation #tomfamily #SoviAI
