# Edexcel GCSE Maths Calculator Paper June 9th 2016 Potential Topics watch

1. ESSENTIALS

Quadratics using formula (beware of negative "b" values)
Sine and Cosine
Trigonometry and Pythagoras
Bounds calculations (give answer to "suitable" number of decimal places)
Algebraic fractions
Indices (negative/ fractional)
Estimate of mean from frequency tables
cumulative Frequency?
Area and circumference of Circles
Volumes and Areas of 3D Shapes ( frustums, spheres, cones, pyramids)

Trial and Improvement
Simultaneous Equations (linear, maybe with decimal answers)
Simultaneous Equations (with one quadratic)
Exchange Rates
Compound Interest
Similar Shapes (area and volumes)
Stratified Sampling
Percentage Increase/ Decrease
Histograms (complete Table and "graph"-type, and other types)
Enlargement (maybe negative scale factor)

Stem and Leaf
Pie Charts
Recipes
Scatter Graphs
2. Non-right angled triangles Hints (sine and COSINE rules)

When finding a length, if you are given the other 2 lengths and the ENCLOSED angle, use the COSINE rule.
If you don't have the above, go straight to the sine rule.

When finding an angle, if you are given the 3 lengths, use the COSINE rule.
If you don't have all 3 lengths, go straight to the sine rule.
3. Thanks for these!
4. Transformations of sin and Cosine curves
5. even vectors
6. (Original post by unknown2914)
even vectors
...but vectors came up in non-calculator so unlikely.
7. Thankyou! What about bearings? And congruend triangles or geometry questions?

ya even tht
9. what do u mean beware of negative b in the quadratic formula, that's one of the main things to do while using the formula
10. thanks for this

Some people make the mistake of whether the -b is a negative or not. So for example, the b value could be '-4', therefore people end up putting -b as -4 when really it's -(-4) which is +4

No this is not the problem. It is when a -b value is put into the root, the calculator squares b and then puts a negative sign in front of it; this is not what you want !!!

Oh okay, that's what happens at our school a lot, thanks for correcting me though.
