Deveno said:<v,w> is going to be some complex number. take its real part.
for example:
<(2+3i,4-5i),(3,1-i)> = (2+3i)(3) + (4-5i)(1+i) = 6+9i + (4-(-5) + (4 - 5)i)
= 6+9i + 9-i = 15+8i, and the real part of this is 15.
Re: definition is a term used in math to indicate that something is being redefined or clarified. It is often used when introducing a new or more specific definition for a mathematical concept.
Equations are mathematical statements that use symbols, such as letters and numbers, to represent relationships between quantities. They typically involve an equal sign (=) and can be solved to find the value of the unknown quantity.
To solve a math equation, you need to isolate the variable (unknown quantity) on one side of the equal sign and perform the same operations on both sides until the variable is alone. Then, plug in the known values and solve for the variable.
An expression is a mathematical phrase that may contain variables, numbers, and operations, but does not have an equal sign and cannot be solved. An equation, on the other hand, has an equal sign and can be solved to find the value of the unknown quantity.
Equations and solutions are fundamental concepts in math that are used to solve real-world problems and make predictions. They also help develop critical thinking and problem-solving skills, which are important in various fields, including science, engineering, and economics.
