I am student 12th and my best subject Maths

sin(10)sin(30)sin(50)sin(70) = 116

Let be an acute angle such that sin + cos = a, Prove that: sin + cos = 1 3a + 3a a.

Let be an acute angle such that sin + cos = a, Prove that: sin + cos = 1 3a + 3a a.

Please put in discussion post format. Problem is below solve the equation, giving the exact solutions which lie in [0, 2) 19. sin (x) = cos (x)

You may either enter your answers directly into the quiz via keyboard (this is time-consuming) or print it, solve the problems by hand, and then scan it and submit the scans.

Explain and solve important trigonometric identities (sin + cos = 1, tan + 1 = sec) with step-by-step examples. Include practice problems on angles, values of trigonometric functions, and real-life applications.

Tan4x = 4Tanx(1-Tanx)/1-6Tanx+Tanx

Tan(/4+x)/Tan(/4-x)=(1+tanx/1-tanx)

: sin 30 + cos 60 = ? Solution: sin 30 = 1/2 cos 60 = 1/2 , = 1/2 + 1/2 = 1
