Mind Mapping applications are effective tools for students to visually organize their thoughts, transitioning from concrete ideas to more abstract concepts. These tools provide a clear visual representation of how ideas and information are connected, making it easier to identify areas that need further development.

mind maps

Mind Mapping applications are tools that allow students to develop a physical representation, a blueprint of their thinking that goes from the concrete to the more abstract. Mind Maps provide a clear and organized visual snapshot of how the ideas and information are outlined in one’s head. This way one can see where ideas need to be further developed and how all the information is linked.

6 Trig Functions

The secant sec(A) is the reciprocal of cos(A); i.e. the ratio of the length of the hypotenuse to the length of the adjacent side
Pronounce cot as "cotangent theta".
The cotangent cot(A) is the reciprocal of tan(A); i.e. the ratio of the length of the adjacent side to the length of the opposite side; so called because it is the tangent of the complementary or co-angle
Pronounce sec as "secant theta"
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: so called because it can be represented as a line segment tangent to the circle
Pronounce csc as "cosecant theta"
The cosecant csc(A), or cosec(A), is the reciprocal of sin(A); i.e. the ratio of the length of the hypotenuse to the length of the opposite side; so called because it is the secant of the complementary or co-angle
the angle is called the Pronounce tan as "tangent theta".
Subtopic
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: so called because it can be represented as a line segment tangent to the circle, that is the line that touches the circle
where the angle is called the Pronounce cos as "cosine theta".
