The cosine rule The cosine rule is a fundamental concept in geometry that can be used to solve a variety of problems. However, it can be difficult to understand and apply, especially for students who are just learning about it. That's why we created a new interactive simulation that makes learning the cosine rule fun and easy. Our simulation allows you to practice using the cosine rule in a variety of situations. You can also see the results of your calculations in real time. We believe that our simulation is the best way to learn the cosine rule. It is interactive, engaging, and easy to use. We hope you enjoy using it! In this blog post, we will provide a brief overview of the cosine rule and how our simulation can help you learn it. We will also discuss some of the features of our simulation that make it so effective. What is the Cosine Rule? The cosine rule is a formula that can be used to find the length of any side of a triangle, given the lengths of the other two sides and th

Denary to Binary Conversion Denary to binary conversion is a fundamental concept in computer science and digital electronics. It involves transforming a base 10 number, which represents the number system we commonly use, into a base 2 number, which is the language used by computers to store and manipulate information. As far as the computer science students at GCSE and A Level are concerned, it is a vital concept to be mastered. The process of converting from denary to binary involves repeatedly dividing the denary number by 2 and observing the remainders. The remainders represent the digits of the binary number, with a 0 indicating a 0 digit and a 1 indicating a 1 digit. The quotients are then used to perform further divisions, continuing the process until the quotient reaches 0. Here's a step-by-step explanation of the conversion process: Start with the denary number. Divide the denary number by 2. Note the remainder. This will be the least significant bit (LSB) of the binary

Iteration for GCSE and A Level   Aim: To use iteration to find an approximate solution to the equation x² - x - 5 = 0. Step 1: Rearrange the equation to get the iterative form, x² = x + 5.. Step 2: Divide both sides of the equation by x to get x = 1 + 5/x - the iterative form. Step 3: Now write it in this form: x n+1 = 1 + 5/x n Step 4: Use an initial value to trigger off iteration such as x 0 = 1. Step 5: We can now use the iterative formula. We can start with an initial guess of x 0 =1 and then use the iterative formula to repeat, until we get a value that becomes relatively constant. Step 6: Approximate the value to the required decimal places and it is a root of the quadratic equation. x(0) = 1 x 1 = 6.0   x 2 = 1.83333333333   x 3 = 3.72727272727 x 4 = 2.34146341463   x 5 = 3.13541666667   x 6 = 2.59468438538 x 7 = 2.92701664533 x 8 = 2.708223972 x 9 = 2.84622839606 x 10 = 2.75671074286   x 11 = 2.81375576416   x 12 = 2.77698436505 x 13 = 2.80051427834
