People who contributed to trigonometry?
Trigonometry, the branch of mathematics that deals with the study of angles and triangles, has a rich history spanning many centuries and cultures. Many notable mathematicians, astronomers, and scholars have contributed to the development of trigonometry over the years. Here are some of the most significant contributors to the field: Hipparchus (190-120 BCE): A Greek astronomer and mathematician who is considered the father of trigonometry. He developed the first trigonometric table and used trigonometry to make astronomical calculations. Ptolemy (90-168 CE): Another Greek astronomer and mathematician who made significant contributions to trigonometry. He wrote a book called "Almagest" which included trigonometric tables and formulas for calculating angles and distances. Aryabhata (476-550 CE): An Indian mathematician and astronomer who developed trigonometric tables and formulas for calculating the sine and cosine functions. Al-Khwarizmi (780-850 CE): A Persian mathematician who wrote a book called "The Compendious Book on Calculation by Completion and Balancing," which included trigonometric tables and formulas. Regiomontanus (1436-1476): A German mathematician and astronomer who made significant contributions to the study of trigonometry. He worked with his teacher, Georg von Peurbach, to improve trigonometric tables and develop the principles of spherical trigonometry. Leonhard Euler (1707-1783): A Swiss mathematician who made significant contributions to many fields of mathematics, including trigonometry. He developed the modern notation for trigonometric functions and made important discoveries about their properties and relationships. Overall, these mathematicians and astronomers, along with many others, have made significant contributions to the development of trigonometry over the years. Their work has helped to lay the foundation for modern mathematics and science, and their influence can still be seen in the study of angles and triangles today.
Can you transform sine functions into cosine functions?
If you know the measure of one angle, and the length of one side of a triangle, you can find the measures of the other sides and angles. From there, you can find the values of the other trig functions. cos (x) = sin (90-x) in degrees there are other identities such as cos^2+sin^2=1, so cos^2=1-sin^2
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.
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 value 10b when b 9?
If b = 9 then the value of 10b is 90
Why do trigonometric ratios do not depend on the size of the right triangle?
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
If 36 is 90 of value what is the value?
40 x 90% = 36
How can 0 and 90 degrees be angles for trigonometric functions even though a right-angled triangle can never have them as 1 of its other angles?
Trigonometric functions take, as input, an angle between 0 and 360 degrees, or 0 and 2 pi radians. While it is useful to think of a right triangle on a unit circle, it is more correct to think in polar coordinates, where r=1 and theta equals the angle in question. The cosine and sign function still remain as the x and y values of the point on the unit circle. Even if you remain in rectangular coordinates, there is no problem, as you simply consider that, at 0, 90, 180, 270, and 360 degrees, the right triangle degrades to a straight line of length one.
What is the value of cosx at -90?
at -90 degrees the value of cos(x) is 0.
