Finding Values of 0 Satisfying the Equation 5sin 0 = - 4

In trigonometry, equations involving sine and cosine functions are used to solve various problems in mathematics and physics. One such equation is 5sin 0 = - 4, where 0 represents the angle in degrees. In this article, we will explore the values of 0 between 0° and 360° that satisfy this equation.

The given equation is 5sin 0 = - 4. To solve for 0, we need to isolate the sine function. We can do this by dividing both sides of the equation by 5, which gives us:

sin 0 = - 4/5

To find the values of 0 that satisfy the equation, we need to find the angles whose sine is equal to - 4/5. We can use a calculator or a trigonometric table to find the values of 0.

Using a Calculator

Using a calculator, we can find the values of 0 that satisfy the equation. We can enter the equation sin 0 = - 4/5 and use the inverse sine function to find the values of 0.

Inverse Sine Function

The inverse sine function is denoted by sin^(-1) or arcsin. It returns the angle whose sine is equal to the given value. In this case, we want to find the angle whose sine is equal to - 4/5.

Calculating the Values of 0

Using a calculator, we can find the values of 0 that satisfy the equation. We get two possible values:

0 ≈ -53.13° 0 ≈ -226.87°

Using Trigonometric Identities

We can also use trigonometric identities to solve the equation. One such identity is the sine function's periodicity, which states that sin(0) = sin(0 + 360°) for any angle 0.

Applying the Periodicity Identity

Using the periodicity identity, we can rewrite the equation as:

sin(0) = sin(0 + 360°)

Substituting this into the original equation, we get:

5sin(0 + 360°) = - 4

Simplifying the Equation

We can simplify the equation by using the fact that sin(0 + 360°) = sin(0). This gives us:

5sin(0) = - 4

Solving for 0

We can now solve for 0 using the same method as before. We get two possible values:

0 ≈ -53.13° 0 ≈ -226.87°

In this article, we have found the values of 0 between 0° and 360° that satisfy the equation 5sin 0 = - 4. We used a calculator and trigonometric identities to solve the equation and found two possible values: 0 ≈ -53.13° and 0 ≈ -226.87°.
