Sin 55 cos theta
Webb16 apr. 2024 · sin (55) = cos (t) The easiest way is to know that one graph is a vertical shift of the other. so sine starts at 0 while cosine starts at 1 and doesn't get to 0 until you are at an input of 45 (or pi/2 degrees). so sin (x) = cos (x - 90) = cos (x + 270) and cos (x) = sin (x + 90) = sin (x - 270). Webb28 jan. 2024 · Solution: Find the value of sin (arc cos 15/17) Solution: If cos65° + cos55° = cosθ, find the θ in radians Solution: Find the value of A between 270° and 360° if sin^2A – sinA=1 Solution: Solve for G if csc (11G – 16 degrees) = sec (5G + 26 degrees) Solution: If sinxcosx + sin2x = 1, what are the values of x? Solution: Solve for x, if tan3x=5tanx
