(1+Tan^2A)CotA/Cosec^2A =TaTanA

Prove that sinA +cosA /sinA-cosA +sinA -cosA /sinA+cosA =2/2sinA-1

in triangle ABC, right-angled at B, AB=24 cm,BC=7 cm.Dtermine: (i) sin A,cos A (ii) sin C, cos C

Find the value of sin 31/3

Hi iam a math teacher you can asked me all types of trigonometry questions

Students asked me all types of trigonometry questions

When A=0 Sin20=2Sin0 0=0

Chapter: Trigonometry Topic: Trigonometric Ratios Question: In a right-angled triangle ABC, where B = 90, AB = 6 cm and AC = 10 cm, find sin A.

value of sin(22.5)

1 . Given that SinA = root3/2 and Tan B =1/root3 , then the value of cos(a-b) is
