Simultaneous Equations (GCSE Foundation & Higher) You'll see how to solve 2 linear (x and y only) simultaneous equations. Save this for revision + watch full Simultaneous Equations video on my YouTube channel (LINK IN BIO). 💡 New content every week - follow/ subscribe to stay updated! Q: How do I solve simultaneous equations? A: Eliminate either the x's or y's, solve the remaining equation, then sub the answer back in. #GCSEMaths #GCSEHigher #MathsRevision #ExamRevision #Year11 #Edexcel #AQA #SimultaneousEquations #StudyTok #MathsTok Music: Elliot Nicklin

Repeating decimals are just geometric series in disguise. Converting 0.321 repeating to a fraction? Express it as a series, identify the first term and common ratio, then use the geometric series formula a/(1-r). This is from a real 2016 intro to calculus exam — if you can solve it with no help and in a timely fashion, you’re ready for the test.

Quadratic Simultaneous Equations (GCSE Maths) Quadratic simultaneous equations are one of the most common GCSE Maths exam questions. But many students lose marks because they forget one simple step — substitution. In this video you will learn: • How to rearrange a linear equation • How to substitute into a quadratic equation • How to factorise the quadratic • How to find the coordinate solutions Practice the question at the end and comment your answer. #GCSEMaths #QuadraticSimultaneousEquations #MathsRevision #AlgebraMaths #GCSEExamPreparation #MyExamRevision #GCSETips #RevisionTips #ExamTips

Separable differential equations can look tricky, but they're actually a breeze once you know the steps! Let's break down this simple example and get you ready for your integral calculus exam. Remember, practice makes perfect!

Struggling with integrals? Here’s how to solve a common Year 12 integral using u-substitution. When you see a tricky integral like 3x² * cos(x³), the key is to eliminate the part that’s causing problems. By substituting u = x³, we simplify the integral, perform the calculation, and then substitute back to get the final answer: sin(x³) + C. Follow us for more quick and easy math solutions to help you ace Year 12!

GCSE Maths: Quadratic Tables Explained 📈 Looking for the best way to learn quadratic equations or free GCSE Maths revision? We’ve got you covered. Here is the breakdown: Find the Pattern: Quadratic equations usually have an x squared term. This means the graph will be a U-shape (parabola), so look for symmetry in your y-values. Substitute Carefully: Replace the x in the equation with the number from the table. If x is negative 3 and the equation is x squared, remember that negative 3 times negative 3 equals positive 9. Work Through the Terms: Calculate the x squared part first, then add or subtract the x term, and finally add the constant number at the end. Double Check: If your points don’t form a smooth curve when you plot them, go back to your table. A single wrong calculation will break the symmetry! This is essential for Paper 1 and Paper 2.
