How do we find the solution of a trigonometric equation if it has only one term?

If a trig equation can be solved analytically, these steps will do it:

1. Put the equation in terms of one function of one angle.
2. Write the equation as one trig function of an angle equals a constant.
3. Write down the possible value(s) for the angle.
4. If necessary, solve for the variable.

How do we find the solution of a trigonometric equation if it is in quadratic form?

How to Solve a Trigonometry Equation Using the Quadratic Formula

1. Identify the values of the a, b, and c in the formula.
2. Fill in the quadratic formula with these values and simplify.
3. Find approximate values for sin x from the solved form.
4. Use a table of values to find approximate angles with these sines.

How do you isolate X from COS X?

The trig operator in the example is cosine, so isolate the x by taking the arccos of both sides of the equation: arrccos 2x = arccos 1/2, or 2x = arccos 1/2.

How do you solve trigonometric problems?

How do you find the zeros of a trig function?

Trigonometry Examples

1. To find the roots/zeros, set sin(x) equal to 0 and solve. sin(x)=0.
2. Take the inverse sine of both sides of the equation to extract x from inside the sine. x=arcsin(0)
3. The exact value of arcsin(0) is 0 . x=0.
4. The sine function is positive in the first and second quadrants.
5. Subtract 0 from π .

How do you solve cosx = 0?

How do you solve cosx=0? In the trigonometric circle you will notice that cos (x)=0 corresponds to x = π 2 and also x = − π 2. Additionally to these all the angles that make a complete turn of the circle ( 2kπ) plus ± π 2 correspond to cos (x)=0.

How do you find cos(x)=0 in trigonometry?

In the trigonometric circle you will notice that cos (x)=0 corresponds to x = π 2 and also x = − π 2. Additionally to these all the angles that make a complete turn of the circle ( 2kπ) plus ± π 2 correspond to cos (x)=0.

What is the value of arccos(0) in cos(x)?

cos (x) = 0 cos (x) = 0 Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. x = arccos(0) x = arccos (0) The exact value of arccos(0) arccos (0) is π 2 π 2.

How do you find the first elements of cos(x)=0?

In the trigonometric circle you will notice that cos (x)=0 corresponds to x = π 2 and also x = − π 2. Additionally to these all the angles that make a complete turn of the circle ( 2kπ) plus ± π 2 correspond to cos (x)=0. So you have: If you try to see which are the first elements (from k =0, 1,2…of this series you will find that they are:
