Moreover, this also implies that the function \(f\left( {x,y} \right)\) has a horizontal tangent plane at the point \(\left( {{x_0},{y_0}} \right)\) and helps us to determine extrema. Relative Minimum A point \(\left( {{x_0},{y_0},f\left( {{x_0},{y_0}} \righ...
To find the angle between two curves intersecting in a point, we will calculate the angle between the tangent vectors to the curve at the common point. If we are interested in the acute angle of intersection, then we will take the positive argument of inverse cosine function: {eq}\...
Area of a triangle is the region covered by its three sides in a plane. Area of a triangle is equal to half of product of its base and height. Find the area using heron's formulas and SAS condition, with examples at BYJU'S.
It's easy to think of maps as sets of visual directions. Whether you're trying to get to the top of Mount Everest or to a friend's new home, a map can help you find your way. But maps can do more than help you figure out where you are and where you're going. They are repre...
