That's not a nice equation but here's what I might do: write it as 90 sin x= 144- 155.8 cos xnokia8650 said:Hi
I was wondering if there is a non-numericla way to solve the following equation:
144 - 90sin x - 155.8cos x = 0
Thanks
To solve an equation involving sin and cos terms, you must use trigonometric identities and algebraic techniques to manipulate the equation until it is in a form where you can isolate the variable. This may involve using the Pythagorean identity, double angle formulas, or other trigonometric identities.
The key steps in solving an equation involving sin and cos terms are:
1. Simplify the equation by using trigonometric identities.
2. Use algebraic techniques to isolate the variable.
3. Check your solution by plugging it back into the original equation.
Yes, you can use a calculator to solve an equation involving sin and cos terms. However, it is important to have a basic understanding of trigonometric identities and how to manipulate equations before relying on a calculator.
Yes, there are a few special cases when solving an equation involving sin and cos terms. These include when the equation has an identity solution (such as sin x = sin x) or when the equation has an extraneous solution (such as sin x = -1). It is important to check for these cases and eliminate any extraneous solutions.
Yes, you can use the inverse sine or cosine function to solve an equation involving sin and cos terms. However, this method may not always yield the complete solution set, so it is important to check for any additional solutions by using trigonometric identities and algebraic techniques.
