Assam has become the 36th State/UT to implement One Nation One Ration Card (ONORC). With this, the ONORC programme has been successfully implemented in all states and Union Territories, making food security portable throughout the country. The government has also rolled out the 'MERA RATION' mobile application to take maximum advantage of the ONORC plan. The mobile app is providing a host of useful real-time information to the beneficiaries and is available in 13 languages. The ONORC scheme is being implemented under National Food Security Act (NFSA).
If tan α = 1/2, tan β = 1/3, then find α + β.
Find the simplified value of:
(tan 40 º + tan 20 º )/(1 - tan 40 º tan 20 º)
In a right triangle ABC, angle B = 90°. If tan A = 3/4 and the length of the hypotenuse is 25 cm, find the area of the triangle.
sin2 12˚ + sin2 14˚ + sin2 16˚ + sin2 18˚ + ……… + sin2 78˚ =?
Simplify the following trigonometric expression: 12 cos 68° cosec 22° - 3 cot 72° cot 18°
If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
If α means +, β means -, ɣ means x, θ means ÷ then 30 θ 10ɣ 5α 10β20 is
If x tan 60° + cos 45° = sec 45° then the value of x2 + 1 is
