revision-guideNational 5 Maths - Working with the graphs of trigonometric functions Revise the relationship between trigonometric formula and graphs as part of National 5 Maths.

The graphs of sine and cosine are included ... equations that are always true. Each trigonometric function also has an inverse that can be used to find an angle from a ratio of sides.

but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.

This applet shows how the graphs of sin(θ) and cos(θ) follow directly from the definition of these functions. Move the slider to change the angle. Observe that after the point moves once around the ...

Students are also taught many formulas in CBSE Class 12, especially in calculus chapters like Inverse Trigonometric Functions. Formulas, theorems and other maths rules help simplify equations and ...

Principal Value: The range of an inverse trigonometric function is the principal value branch and those values which lie in the principal value branch is called the principal value of that inverse ...
