Convergence and Divergence
In Sequences and Series, we can find whether the given function converges or diverges. A function is said to converge if its limit value exists and is finite. A function is said to diverge if its limit value does not exist (or rather approaches infinity).
Convergence and Divergence in sequences:
Congruence and geometry of size
Congruence: If two objects are of same exact shape and same exact size, then they are called congruent objects. The congruent objects are more like duplicates of each other and fit perfectly when placed on top of each other.
In geometry, congruence is an important property and whenever two geometric shapes have same shape and length, then the angles of one shape are also equal to the other.
Angle is the measure of rotation formed between two rays. In trigonometry, angles play a huge role in determining the appropriate trigonometric function values. One complete rotation gives an angle of 360°. Depending on the direction of rotation, angles can be positive or negative!
