However, if we follow the formula to solve the questions, then it will be fine.
Thus, good luck ! :)
Here are some equivalent trigonometric formula:
sin x = cos (π/2 – x) | cos x = sin (π/2 – x) | sin (π/2 + x) = cosx | cos (π/2 + x) =-sinx |
tan x = cot (π/2 – x) | cot x = tan (π/2 – x) | tan (π/2 + x) =-cotx | cot (π/2 + x) =-tanx |
csc x = sec(π/2 – x) | sec x = csc(π/2 – x) | csc (π/2 + x ) =secx | sec (π/2 + x )=-cscx |
If you are still confused to these formula, take your time and feel free to watch the video! You will learn much!
