Question

Express all other trigonometrical ratios in terms of cos

Answer 1

Hi Friend !!!

Here is ur answer !!!

sin A= √1-cos²A

cosA = cosA

tan A =
$= \frac{ \sqrt{1 - {cos}^{2} } }{cos}$
Cot A
$= \frac{cos}{ \sqrt{1 - {cos}^{2} } }$
cosec A
$= \frac{1}{ \sqrt{1 - {cos}^{2} } }$
sec A = 1/cos A


Hope it helps u : )

Answer 2

Heya dear !!!




★Sin² theta + Cos² theta = 1


Therefore,


Sin theta = ✓ 1 - Cos² theta



********************************************



★Cos theta = Cos theta



*****************************************






★Sec theta = 1/ Cos theta



*******************************************




★Tan theta = Sin theta / Cos theta


Therefore,




Tan theta = ✓ 1 - Cos²theta / Cos theta


********************************************



★Cot theta = Cos theta/ Sin theta



Cot theta = Cos theta/ ✓1 - Cos²theta
