Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
How do I solve the equation
![The equation presented in the image is:
\[ \sin^2(\theta) + \cos^2(\theta) = 1 + \cos(\theta) \]
This equation is a trigonometric identity involving sine and cosine functions, common in trigonometry studies. According to the Pythagorean identity, \(\sin^2(\theta) + \cos^2(\theta) = 1\).
The equation is accompanied by the range of \(\theta\):
\[ 0 \leq \theta < 2\pi \]
This range specifies that the angle \(\theta\) is measured in radians and is within one full rotation around the unit circle.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff5445541-3bd8-48a0-bfe5-5b2c37f58de6%2F8a59145b-2be4-4168-8497-933879a5e50a%2F2ezrs1a_processed.jpeg&w=3840&q=75)
