Because in second angle both quaderent comes negative that's why we cant use second angle method
Second and fourth angle projections are not commonly used in mechanical drawing because they can lead to confusion and misinterpretation of the object's geometry. In the first angle projection, the object is placed in the first quadrant, which aligns with how engineers and manufacturers typically visualize the part in relation to its views. The third angle projection, which is the most widely used, presents views in a more intuitive manner, allowing for clearer communication of dimensions and features. Therefore, the first and third angles are preferred for their clarity and consistency in representing 3D objects in 2D space.
you do not use it when you multiply
Second and fourth angle projections are rarely used in technical drawing because they can lead to confusion and misinterpretation. These methods do not align with standard practices, which favor first and third angle projections for clarity and consistency across industries. By adhering to the more commonly accepted projections, engineers and designers ensure that their drawings are easily understood by others. Thus, using first and third angle projection simplifies communication and reduces the risk of errors in manufacturing or assembly.
cross product method is multiplying the numerator of the first factor to the denominator of the second factor and multiplying the denominator to the numerator of the second factor.
triangles are the second strongest shape next to the arch
In 1st angle projection the front view will be in the top of the xy plane and the top view will be in the bottom of the xy plane .In 3rd angle projection the top view will be in the top of the xy plane and front view will be in bottom of the xy plane. dis will give a clear view.i hope u know dis... but in 2 angle projection both the views(front and top) will be in the top of the xy plane and in 4th angle projection both the views (front and top) will be in the bottom of the xy plane... since both the views will be in one side of the xy plane, its not possible to draw... both views will merge... to get more clear view, refer any basic engineering drawing book.......
because in 2nd and 4th angle,both the view is going to overlap with each other,so we cant able to visualise the drawing properly,so we are not drawing in 2nd and 4th angle. kash answer kash_115@yahoo.com

It depends on what the second method is!
Heun's method is a numerical technique used to approximate solutions to second-order differential equations. It involves breaking down the problem into smaller steps and using iterative calculations to find an approximate solution. This method is commonly used in scientific and engineering fields to solve complex differential equations that cannot be easily solved analytically.
yes, there is. On the back of your ticket you can fill in your information for a second chance drawing. There is also an address on the back where you can mail in your ticket.

An arc is a portion of a circle. The default method for drawing arcs is to specify three points-the start point, a second point, and the endpoint. You can draw an arc using several different methods.
