What are the quadrant angles?
Quadrant angles are angles formed in the coordinate plane by the x-axis and y-axis. Each quadrant is a region bounded by the x-axis and y-axis, and is numbered counterclockwise starting from the positive x-axis. The angles in each quadrant have specific characteristics based on their trigonometric ratios, such as sine, cosine, and tangent values. In trigonometry, understanding quadrant angles is crucial for determining the sign of trigonometric functions and solving equations involving angles.
People who contributed to trigonometry?
Some key contributors to the development of trigonometry include ancient civilizations such as the Babylonians and Egyptians, who used rudimentary trigonometric concepts for practical purposes. The Greek mathematician Hipparchus is often credited with formalizing the field of trigonometry, introducing the trigonometric functions and developing the earliest trigonometric tables. Later, Islamic mathematicians such as Al-Battani and Al-Khwarizmi made significant advancements in trigonometry, further expanding its applications in astronomy, geography, and mathematics. These early pioneers laid the foundation for the modern study and application of trigonometry in various fields.
How are the graphs of sec x and csc x related?
They are co-functions meaning that 90 - sec x = csc x.
What trig function has a value of 1?

What trigonometric value is equal to cos 62?
The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
How do you graph trigonometric functions with a degree in the parenthese?
Look on a unit circle graph and see what kind of pi it has. For example 90 degrees is pi/2
What are the functions of an acute angle of a right triangle?
Any function whose domain is between 0 and 90 (degrees) or between 0 and pi/2 (radians). For example, the positive square root, or 3 times the fourth power are possible functions. Then there are six basic trigonometric functions: sine, cosine, tangents, cosecant, secant and cotangent, and the hyperbolic functions: sinh, cosh, tanh etc. These, too, are not specific to acute angles of a right triangle but apply to any number.
How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
What is the absolute value of 90?
Absolute value of 90 is 90.
What number is the absolute value of -90?
Absolute value of -90 is 90.
Sin30 cos90 sin 90 cos30?
To simplify the expression sin(30°) cos(90°) sin(90°) cos(30°), we first evaluate the trigonometric functions at the given angles. sin(30°) = 1/2, cos(90°) = 0, sin(90°) = 1, and cos(30°) = √3/2. Substituting these values into the expression, we get (1/2) * 0 * 1 * (√3/2) = 0. Therefore, the final result of sin(30°) cos(90°) sin(90°) cos(30°) is 0.
Can angles be represented by a single number?
Yes, angles can be represented by a single number, typically measured in degrees or radians. For example, a right angle is represented as 90 degrees or π/2 radians. This single value conveys the measure of rotation from one ray to another. However, angles can also be expressed in other forms, such as using trigonometric functions, but the numerical representation is the most common.
What is the value of x in a 90 degree triangle with a hypotenuse of 30 and a 45 degree angle x is the opposite of the 45 degree angle us a trigonometric function?
Use and rearrange the sine ratio: 30*sin(45) = 21.21320344 units
What angles are used to relate the values returned by inverse trigonometric functions to angles larger than 90 degrees?
When using inverse trigonometric functions to relate values to angles larger than 90 degrees, we typically use reference angles. Reference angles are acute angles formed between the terminal side of the angle in question and the x-axis. By using reference angles, we can determine the appropriate quadrant and sign for the angle, allowing us to accurately relate the values returned by inverse trigonometric functions to angles greater than 90 degrees.
