Knowledge of mathematics is the pedestal of all sciences
The language-mathematics can trigger mathematical trauma. Mathematical trauma can have serious consequences for students who are affected. They may reject mathematics as something they are not able to do. This can also affect their belief in themselves as been capable to solve some mathematical problems.
Lange and Meaney(2011) describe mathematical trauma as:'being deprived of opportunities for expression, interpretation and agency in relation to mathematics, and hence positioned as passive receivers of superficial mathematical knowledge amounts'. This trauma may seem easy to dismiss but, more research provides evidence that some students experience real distressing trauma while studying mathematics. With us, you will find great algebra tutoring online for your kids anytime; when they are studying or working on homework, before class or after practice. We strive to help students with quality online calculus tutoring. Struggling students find our sessions rewarding as it helps them bridge the learning gap they suffer while in the brick-and-mortar classroom.

Useful mathematical expressions
Laws of Mathematics
- Trigonometrical identities
- Standard Curves
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B – cos A sin B
cos (A + B) = cos A cos B – sin A sin B
cos (A - B) = cos A cos B + sin A sin B
2sin A cos B = sin(A+ B) + sin(A - B)
2cos A sin B = sin(A+ B) – sin(A - B)
2cos A cos B = cos(A+ B) + cos(A - B)
2sin A sin B = cos(A - B) - cos (A + B
Angles having the same trigonometrical ratios:
(i) Same sine: θ and (1800 -θ)
(ii) Same cosine: θand (3600 – θ), i.e. (-θ)
(iii) Same tangent: θand (1800 + θ)
Association laws – for addition and multiplication
Commutative laws-for addition and multiplication
(i) a+b=b + a
(ii) ab = ba
Distributive laws-for multiplication and division
(i) a(b + c) =ab + ac
(ii) (b+c)/a=b/c + c/a (provided a≠0)
(i) Centre at origin, radius r: x2 + y2 = r2
(ii) Parametric equations; x:rcosθ,y=rsin θ
