Can you use Photomath for trigonometry?
Photomath Covering a range from basic math to calculus and trigonometry, Photomath is a great Android app to help explain tricky math sets. It uses a smartphone’s camera pointed at a math problem, analyses the information and gives a detailed-step-by-step answer and explanation.
What is the equation for trigonometry?
Trigonometric Equations and its Solutions
| Trigonometrical equations | General Solutions |
|---|---|
| sin θ = sin α | θ = nπ + (-1)n α, where α ∈ [-π/2, π/2] |
| cos θ = cos α | θ = 2nπ ± α, where α ∈ (0, π] |
| tan θ = tan α | θ = nπ + α, where α ∈ (-π/2, π/2] |
| sin 2θ = sin 2α | θ = nπ ± α |
What does K mean in Photomath?
What is K in Photomath? constant. In the context if a math problem you would encounter in school “k” would be used to represent a constant you have to find the value of, usually when x and y are already used to represent a function. In formulas such as a(e)^kt for interest “k” represents an arbitrary value.

What calculator do I need for trigonometry?
For College Algebra, Trigonometry, Precalculus Algebra & Trigonometry, Geometry for Education, Calculus I and Calculus II: A scientific calculator. A cheap ($9-$20) scientific calculator is all you need. If you are not sure how to tell if a calculator is scientific, it must have a key labeled SIN to be scientific.
What is the best calculator app for trigonometry?
Photomath (Android, iOS: Free) The app handles everything from basic algebra to linear, quadratic, and absolute equations and inequalities, systems of equations, trigonometry, and more with equal aplomb.
Why do you put AK for thousand?
And you would be correct, thanks to the Greeks. K comes from the Greek word kilo which means a thousand. The Greeks would likewise show million as M, short for Mega. So if we stay consistent with the Greek abbreviations, then billion would be shown as a letter G (Giga).
