What is trigonometry? The word trigonometry comes from two Greek words. These two words are trigonon (triangle) and metria (measure). Therefore, trigonometry is a branch of mathematics but especially a branch of geometry, that specializes in the measurement of triangles....
sin(x) is the ratio of the side opposite the angle and the hypotenuse, cos(x) is the ratio of the side adjacent to the angle and the hypotenuse, tan(x) is the ratio of sine and cosine Where is trigonometry used in real life? In real life, trigonometry has applications in many ...

The trigonometric ratios sin θ, cos θ and tan θ of an angle θ are very closely connected by a relation. If any one of them is known, the other two can be easily calculated. Let us see how. Let us again consider the following figure – We have learnt above that Sin θ = $\fr...
What is a center of rotation in geometry? \bar{JK} is tangent to circle P and Circle Q. a) What kind of quadrilateral is JPQK? b) JK = [{Blank}]. At what points does the helix r(t) = (sin t, cos t, t) intersect the sphere x^2 + y^2 + z^2 = 65?

sine function domain and range as we know, the sine function is defined for all real numbers, so the domain of y = sin x is the set of all real numbers, i.e. r. the range of sine function is the closed interval [-1, 1]. that means, -1 ≤ y ≤ 1 or -1 ≤ sin x ≤ ...
It is better to define them as power series: (sum(a,b) means sum from a to b of the given expression, summation sign) sin x = sum(i=0,infinity)(-1)^i x^(2i+1) / (2i+1)! cos x = sum(i=0,infinity)(-1)^i x^(2i) / (2i)! With these definitions, you can prove...
sin x = O(x) when x → 0. sin x = O(1) when x → +∞, x2 + x = O(x) when x → 0, x2 + x = O(x2) when x → +∞, ln(x) = o(x) = O(x) when x → +∞. Attention! The notation with the equal sign "=" uses a "fake equality": it is true that ...
