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:An angle of $90^\circ$ in radians is:The value of $ in(\pi/4)$ is:The identity $ in 2A$ equals:The general solution of $\cos x = 1/2$ is:The angle 90° in radians is:The fundamental Pythagorean identity in trigonometry is:The exact value of cos 60° is:The double angle formula sin 2A equals:The general solution of sin θ = 1/2 is:The principal value range of sin⁻¹(x) is:In a triangle ABC, the Law of Sines states:The Law of Cosines, given sides a, b and included angle C, gives the third side c as:The function f(x) = tan x has vertical asymptotes at:An experiment whose result cannot be predicted in advance is:A random experiment must have possible outcomes numbering:A possible result of a random experiment is called its:The set of all possible outcomes of an experiment is the:The sample space is written with the symbol:Each element of the sample space is called a:The empty set, taken as an event, is called the:The whole sample space, taken as an event, is called the:An event holding just one sample point is called:An event holding more than one sample point is called:For every event A there corresponds the event called:Two events that cannot occur together are called:Simple events of a sample space are always:Events are exhaustive if at least one of them must:The axiomatic approach to probability was developed by:Kolmogorov published that approach in the year:Kolmogorov was a mathematician from:The classical theory assumes that all outcomes are:The classical theory fails for experiments whose outcomes are:Classical probability is the ratio of favourable outcomes to:Rolling one die gives a sample space of size:Tossing two distinguishable coins can end in:
