Project On Mini.

This project involves designing a mini engineering calculator using C language to perform basic arithmetic and trigonometric functions. The calculator takes a number from 1-10 as input corresponding to a mathematical operation. It uses switch conditions to perform the operation based on the input number, with a default statement to handle invalid inputs. The operations include addition, subtraction, multiplication, division, powers, logarithms, and trigonometric functions.

PROJECT ON

Design a mini engineering calculator to support trigonometric


function with basic arithmetic.
Submitted by- Sumit Kumar Mishra.
Institute Name-ISM.
Admission No-1681.

Introduction- Engineering calculator is use to calculating mathematical


equation, This calculator can calculate basic arithmetic and trigonometric
function. The first desktop programmable calculators were produced in the mid
1960s by Mathatronics and Casio. The first programmable pocket calculator was
the HP-65, in 1974, it had a capacity of 100 instructions, and could store and
retrieve programs with a built in magnetic card reader. Two years later the HP-
25C introduced continuous memory, i.e. programs and data were retained
in CMOS memory during power-off. In 1979, HP released the first alphanumeric,
programmable, expandable calculator, the HP-41C. It could be expanded
with random access memory (RAM, for memory) and read-only memory (ROM,
for software).

SYNOPSIS
1. Discription-
This program is taking input as a number from 1 to 10 and all the numbers are
denoting some mathematical operation as below. This program used the switch
condition and every unique no is denoting to operation of this calculator as a case
value. After completing the every case, break is used to terminate the program. If
user not enters the correct value than default statement will remind them.
Scientific calculators are used widely in situations that require quick access to
certain mathematical functions, especially those that were once looked up in
mathematical tables, such as trigonometric functions or logarithms. They are very
often required for math classes from the junior high school level through college,
and are generally either permitted or required on many covering math and
science subjects; as a result, many are sold into educational markets to cover this
demand, and some high-end models include features making it easier to translate
a problem on a textbook page into calculator input, e.g. by providing a method to
enter an entire problem in as it is written on the page using simple formatting
tools.
