2y^1/2 -7y^1/4+ 3 = 0 We need to use a substitution to obtain a quadratic.Let y^1/4 = x (use the y with the smallest fractional power as your substitution)From this, we can s...

The sliding filament theory demonstrates how the muscles in our body contract. As a signal reaches the neuromuscular junction (motor end plate), neurotransmitters such as Acetylcholine will diffuse across...

The product rule states that if y=uv, where u and v are both functions of x, then dy/dx = u(dv/dx) + v(du/dx)Therefore, the differential of 2xe^3...

Sustainability in cities involves improving and developing cities whilst preserving the environment and resources. Sustainable cities must control the use of resources. This can be done by improving the e...

Structure of the protein is easier to understand if we start from the beginning and gradually build up our knowledge. Firstly, proteins are made of amino acids. Each amino acid is made of a central carbon...
