The value of expression (1/cos 290°) (1/√3 sin 250°) is 1) √3/4 2) 4/√3 3) 2/√3 4) √3/2 Answer(2) 4/√3 Solution We know that, cos 290° = cos(360° – 70°) = cos 70° sin 250° = sin (180° 70°) = sin 70° Thus, the given expression will beThe value of sin 180 (sin pi) can be interpreted in terms of different angles like 0°, 90° and 270° Assume that the unit circle in the Cartesian plane is subdivided into four quadrants And we know that the value of sin 180 degrees in the Cartesian plane takes place in the second quadrantGiven cos θ = \(\frac{\sqrt{3}}2{}\) Since, θ is in IIIrd Quadrant So, sin and cos will be negative but tan will be positive We know that, cos 2 θ sin 2 θ = 1 Putting the values, we get Since, θ in IIIrd quadrant and sinθ is negative in IIIrd quadrant
Calculate sin(25)° Determine quadrant Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positiveDetermine angle type 74 is an acute angle since it is less than 90° sin (74) =As we know that sin (theta) is always less than and equal to 1, and sin (90) is equal to 1, which is the highest value Now looking to the question, value of theta and fi will be 90, as 11=2, and 1 can only be possible when both angles are 90 Now theta=fi=90, hence theta fi=180, and cos (180) = 1
