## BASIC Built-in Functions

These are Mathematical functions that are built into BASIC. Some common BASIC functions are shown in the table below:

## BASIC Notation/Symbols

(i)√b2 -4ac/2a

Solution: ((b^2-4*a*c)^(1/2))/(2*a) or ((b**2-4*a*c)^(1/2))/(2*a)

(ii) (x-y)/(x+y)

Solution: (x-y)/(x+y)

(iii) (a+b) + c/Sin d

Solution: (a+b) + c/Sin (d)

(iv)ex+y –Sin (x +ny)

Solution: (e^x+y- Sin(x+n*y))

(v) b = 1/4ac

Solution: b=1/4 (a*c)

(vi) A=∏r²

Solution: PI*r**2 or PI*r^2

EVALUATION

1. What is the meaning of these BASIC functions? LOG, TAN, and ABS.
2. Which Mathematical operator has two notations in BASIC?

## BASIC Programs to Solve Problems

Example 1: Write a BASIC program to find the square root of numbers within a given range.
