When the sum of two angles=90 degrees, they are called complementary angles. We can use following formula →sin(90-θ)=cosθ,cos(90-θ)=sinθ,tan(90-θ)=cotθ,cosec(90-θ)=secθ,sec(90-θ)=cosecθ We...
#As shown in the above diagram The cube has 6 square surfaces.they are equal in area. # The cube has 12 equal edges or sides TOTAL SURFACE AREA OF CUBE:- If edge(side) of the cube = a Then,Total...
For a right angled triangle, with one angle θ (which is not the right angle), the trigonometric ratios are defined as follows: sin θ = Perpendicular / Hypotenuse (corresponding to the angle...
