Question:
in application of trignometry how to find out vales of taking sin or cos or any other please say me the tips to remember
Answer:
Let us take a triangle ABC as shown in the figure.
Here, AB is base, BC is perpendicular and AC is the hypotenuse of the triangle.
Now sin θ = perpendicular/hypotenuse
=> sin θ = BC/AC
cos θ = base/hypotenuse
=> cos θ = AB/AC
tan θ = perpendicular/base
=> tan θ = BC/AB
In this way, we take sin or cos and others.
