Practice CBSE Class 11 Trigonometric Functions — Radian/Degree, Arc Length, Unit Circle, Quadrant Signs, Domain/Range in the app →The relationship between degree measure and radian measure is:In a circle of radius r, an arc of length l subtends a central angle θ (in radians) such that:For all real x, the value of sin²x + cos²x is:Convert 40°20′ to radian measure.A wheel makes 360 revolutions in one minute. Through how many RADIANS does it turn in one second?The minute hand of a watch is 1.5 cm long. The distance the tip moves in 40 minutes is (use π = 3.14):The radius of a circle where a central angle of 60° intercepts an arc of length 37.4 cm (use π = 22/7) is:If two arcs of equal length subtend angles of 65° and 110° at the centres of two circles, the ratio of the radIf cos x = -3/5 and x lies in the THIRD quadrant, then sin x equals:If cot x = -5/12 and x lies in the SECOND quadrant, then sin x equals:In which quadrant is tan x POSITIVE while sin x is NEGATIVE?The DOMAIN of y = tan x is:sin(2nπ + x) equals (for any integer n):The RANGE of y = sec x is:At which of the following x-values is cos x equal to zero?The value of cos(-π/3) is:6 radians converts to approximately:
