Trigonometry is an important part of Quantitative Aptitude section which gives students a tough time with its complex formulas and questions.
Trigonometry is a major branch of mathematics that deals with angles and lengths of right triangles. Trigonometry is used in astronomical studies and other science fields.
There are a total of 6 trigonometric functions namely sin, cos, tan, sec, cosec and cout. There are trigonometric ratios that help to get the current length and angle.
All the formulas, tricks and questions of trigonometry revolve around these 6 functions. Candidates can check the details of Trigonometry including formulas, tricks and questions.
Trigonometry Shortcut Tricks
Important concepts to solve a specific type of question
If a + b = 90°
Results that are always true:
(i) sin A. sec B = 1 or sin A = cos B
(ii) cos A. cosec B = 1 or sec A = cosec B
(iii) Tan A. Tan B = 1 or Tan A = Coat B
(iv) cot a. cot b = 1
(v) sin²A + sin² B = 1
(vi) cos² A + cos² B = 1
Important Trigonometry Formulas for Sum and Difference of Two Angles
(1) sin (a + b) = sin. cosB + cosA sinB
(2) sin (a - b) = sin. cosB - cosA sinB
(3) cos(A+B) =cosA. cosB - sinA sinB
(4) cos(A-B) = cosA. cosB+sinA sinB
(5) 2 sinA.cosB = sin(A+B)+sin (A-B)
(6) 2 whips. sinB = sin(A+B)-sin (A-B)
(7) 2 sew. sinB = cos(A-B)-cos(A+B)
(8) 2 cosA.cosB = cos(A+B)+cos(A-B)
(9) sin²A-sin²B = sin(A+B). sin (a-b)
(10) cos²A-cos²B = cos(A+B).cos (A-B)
