### Is a level maths hard?

A Level Maths is not harder than other subjects at A Level – however this doesn’t mean you won’t have to work hard – of course you will. There might be times when you feel overwhelmed or confused, just like you would when trying to write an extended A Level essay on Shakespeare.

#### What is the trapezium rule formula?

To be more precise, when it is difficult or impossible to find the exact value of a given definite integral, we use a method known as “The trapezium Rule” to find its approximate value. We draw the curve y = f(x) between x = a and x = b and estimate the area under the curve by using various trapeziums.

**What is R binomial formula?**

The bottom number of the binomial coefficient is r – 1, where r is the term number. a is the first term of the binomial and its exponent is n – r + 1, where n is the exponent on the binomial and r is the term number. b is the second term of the binomial and its exponent is r – 1, where r is the term number.

**What is the formula of RTh?**

Calculate RTh = VTh / IN. Alternate method (for circuits that consist only of independent sources and resistors).

## What is the formula of binomial?

by finding the rth entry of the nth row (counting begins with a zero in both directions). Thus, the powers of (a + b)n are 1, for n = 0; a + b, for n = 1; a2 + 2ab + b2, for n = 2; a3 + 3a2b + 3ab2 + b3, for n = 3; a4 + 4a3b + 6a2b2 + 4ab3 + b4, for n = 4, and so on. …

### Is binomial theorem hard?

The Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly. But with the Binomial theorem, the process is relatively fast!
