basic trigonometry : Trigonometry is a branch of mathematics which deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right triangles). See also: Computers & Math Mathematics Math Puzzles Triangles on a sphere are also studied, in spherical trigonometry. Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions. Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science and precalculus. For example, the robotic arm on the International Space Station is operated by controlling the angles of its joints. Calculating the final position of the astronaut at the end of the arm requires repeated use of the trigonometric functions of those angles..

basic trigonometry : An angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. See also: Computers & Math Mathematics Angles provide a means of expressing the difference in slope between two rays meeting at a vertex without the need to explicitly define the slopes of the two rays. Angles are studied in geometry and trigonometry..

Question : http://tinypic.com/view.php?pic=iwptfl&s=3 i get everything except the answer. how did they solve after tan b =1.33 ? how do i plug it into the calculator? any other helpful words? any basic trig help?

Answer : tan = opposite side /adjacent side so 4/3 = 1.333333333333333333333333, which can be nicely written as 1.33 typing it into your calculator depends on the calculator for some, you may have to type in 1.33 and then press the tan^-1 button some press the tan^-1 button first, then 1.33 you must make sure that your calculator is in degrees for this question you will be able to tell if it is by a sign in the corner: "deg" degrees, "rad" radians... go for deg..   More from Yahoo Answers

Question : Can you help me answer this question that I have on my trig test. Define the basic 3 trigonometric functions. Give examples that explain how to solve for both angles and sides of triangles. Also give at least two real-life examples of how trig can be used.

Answer : sine= opp/hyp cosine= adj/hyp tangent= opp/adj Law of Sine= sinA/a = sinB/b = sinC/c Law of Cosine um....well you use trig in physics like to predict where the ball you have thrown will be in x amount of seconds. um..then second not sure. but we use trig a lot...   More from Yahoo Answers
