Scientific numbers

Example 1

This example shows operations with exponents and roots.

Example 2

Orbital velocity computation.

Example 3

The satellite runs along a round orbit with a rotational period of T = 88 min. What is its linear velocity v, since we know that its orbit is located at a distance of h= 200 km from the Earth's surface?

Solution:

Example 4

This example shows that when we need to involute a function, it is enough to place the exponent value by its symbol. There is no need to put the whole expression into the brackets and involute it. Read more »

Scientific numbers

Scientific numbers are represented by multiplying the mantissa (significant part) by the exponent. This number class is the most used.

Numbers

Numbers are entered by simple keyboard typing.

Real (scientific) numbers

Real numbers consist of digits and a decimal point. 

Example: 

Enter in sequence: "12345.678".

Result:

Scientific numbers in the exponential expressions are entered by Nth multiplying.

Example:

Enter: "7.89"[*]"10"[^]"5".

Result:
