Interconnected collagens II, IX and XI form a reticulate structure, and proteoglycan fills the web gap and binds to a large amount of water, which ensures the structural integrity and elasticity of articular cartilage (Xie et al., 2019). The degeneration of ECM is related to collagenase and ...
Prove that |cos x - cos y| less than or equal to |x - y| if x greater than or equal to 0. Verify whether the following equation is an identity. (5 cos x - 2 sin x)^2 + (2 cos x + 5 sin x)^2 = 29 Prove the identity. cos(x + pi/2) = -sin x. ...
Show that e−ix=cos,x−i,sin,x. Exponential and Trig-functions: To prove the given identity, we'll simplify the left-hand side expression or exponential expression using the general power series of exponential function ex. ex=1+x+x22!+x33!+x44!+x55!+x66!+x77!+… After that, ...
