Radian Measure | Definition, Equation & Formula from Chapter 30/ Lesson 10 43K Read the definition of a radian. Understand what a radian measure of an angle is, and learn how to find the radian measure using the radian formula. Discover how to convert a degree measure into a radian measur...
How do I find the radian answer to inverse trig functions? Can the inverse operation of f(x)= \frac{2x+3}{5x-2} be f^{-1}(x)= \frac{-2x-3}{-5x+2} ? How do you find the inverse function of x in F(x)= 2 e^(3x)?
Keep in mind that inverse sine yields two solutions; your calculator will only give you one of these solutions. Examine the angle you were asked to find. If it is obtuse, it measures more than 90 degrees. If you are unsure whether the angle is obtuse or acute, measure it with a protra...
How would you find the additive inverse of a number 'A'? Answer and Explanation: Learn more about this topic: Additive Inverse Definition & Examples from Chapter 3/ Lesson 2 95K The additive inverse is a specific number, and every real number has one! That is, these inverses occur in pa...
How do you Find the Length of an Arc Without the Radius? To find the arc length, we definitely need the radius of the circle and central angle. But when the radius is not given, then either the sector area or the chord length might have been given. Use the following formulas to solve...
Now you know how easy it is to convert between radian and degree measurements! Knowing how to make this conversion will come in handy when studying different topics within geometry such as trigonometry or circles. With just a little practice and some basic understanding of these concepts, you ...
Q.1. How do you find cos 120 without a calculator?Ans. You can use both the following formulasi) cos (180° –θ) = – cosθ orii) cos (90° + θ) = – sinθQ.2. What is cos 120 in radians?Ans. In radian, the value of cos 120 is 2π/3 i.e equal to -1/2....

Remember, the unit circle can be used to find two unknown sides of a right triangle with a 30-degree angle and whose longest side, or hypotenuse, is a length of 7. Let's give it a try. Take note of where 30° is on the unit circle. Use that line and the x-axis to create a...
